Revolutionizing Cancer Care with Stem Cell–Derived Exosomes and NK Cell Therapy | ANEW Ep 101

In this groundbreaking episode of the ANEW Insight Podcast, Dr. Supatra Tovar sits down with board-certified neurosurgeon and visionary founder of ReCELLebrate, Dr. Jeff Gross, to explore one of the most exciting frontiers in modern medicine—stem cell–derived exosomes and natural killer (NK) cell therapies. With decades of experience in neurosurgery and a passion for innovation, Dr. Gross shares how he transitioned from traditional spine surgery into regenerative medicine, where cutting-edge science is transforming cancer treatment, longevity, and immune health.

Listeners will learn how stem cell–derived exosomes act as powerful biological messengers—1/1000th the size of a cell—that selectively eliminate cancer cells and senescent “zombie” cells while preserving healthy tissue. Dr. Gross explains the remarkable role NK cell–derived exosomes play in bolstering the immune system, targeting abnormal cells, and potentially supporting cancer remission and prevention. These advanced therapies could one day replace invasive procedures like mastectomies, delivering targeted, localized treatments while also circulating systemically to prevent cancer spread.

The conversation also tackles the controversial history of stem cell research in the U.S., why Europe and Asia have been decades ahead in adopting these therapies, and the corporate and political influences that have slowed access to life-changing biologics. Dr. Gross addresses common misconceptions about stem cell sourcing, emphasizing the rigorous FDA-regulated, ethical donor process used in regenerative medicine.

Dr. Tovar and Dr. Gross delve into the epigenetic factors that influence cancer risk, such as chronic inflammation, diet, sleep, stress, and environmental exposures. They discuss how lifestyle interventions—from anti-inflammatory nutrition to hormetic stressors like cold plunges and sauna—can optimize natural killer cell function and support long-term health. The episode also examines how refined sugar, processed animal proteins, and other inflammatory foods impact immune surveillance and cancer proliferation.

This in-depth conversation bridges precision medicine, oncology, and wellness, offering hope for a future where cancer care is more effective, less invasive, and deeply personalized. Whether you’re a patient, caregiver, healthcare professional, or simply curious about longevity science, this episode will expand your understanding of the next wave in medical innovation.

Dr. Supatra Tovar: 0:00

Hello and welcome to the ANEW Insight podcast. I am Dr. Supatra Tovar and I am thrilled to have board certified neurosurgeon and visionary founder of ReCELLebrate Dr. Jeff Gross with us today. Dr. Jeff. Welcome. After decades in conventional neurosurgery, Dr. Gross transitioned into the frontier of stem cell and exosome therapies becoming a pioneering figure in the use of activated natural killer cell derived exosomes for cancer treatment and immune optimization. He is one of only a handful of specialists in the world with access to these potent exosomes, Yeah, he is really, really nerdy. Oh my gosh, Dr. Gross. Seriously, this is some really exciting stuff

Dr. Jeff Gross: 0:03

We have therapy, we have time, we have anti-inflammatories, we have injections like epidural injections, for example. And then we have surgery, which is a big jump from all those other things, right? Because the surgeries are sometimes pretty big and open. Not all of them, but it had always been my goal to only do surgery on the people that absolutely had to have it. What else you got doc? You got crystals, you got you know, you know, lasers, you got stem cells, you know, what do you got for me, doc? You know, so. Chance favors the prepared mind. And luckily, in my undergraduate days, a few years back, I might say I studied molecular biology and biochemistry, which is really the stem cell field. And I know a lot had happened in those years. I followed the Christopher Reeves story and the research at that you know, the facilities that were sponsored by a lot of the, the, the donations that went into that thereafter. And I said, you know what, it's been a while. And I loved that topic back then. But it has blossomed into so much more than that that I do spine as just something that comes often and easy to me and everything else is really, really interesting now. So that's, that's, sorry. The long version, if you will. Well, I wanted to include the whole basket of regenerative medicine when I was mentioning that, so people understood where this fit. We have PRP, which is the low end, which is from your own blood. We have stem cells, which can come from your body and from someone else's body, donor. But we've learned that the work of stem cells, in fact, of any cell, but particularly of stem cells in this category come. The business end of stem cells come from these smaller cell to cell communicating factors called exosomes. And what we really mean is stem cell derived vesicles, smaller particles, smaller even than cells by about 1000, 1/1000th. These small communicating particles are doing the work of the stem cells. So, if I gave you stem cells today in your vein, you came in and said, I'd like some stem cells, please. And we put some in your vein, for whatever reason we decide they'd be gone outta your body in 10 to 14 days. I. But the benefits would last longer and perhaps some of them even permanently. And why is that? Because those stem cells have delivered to you, their communicative, activating messages to your cells, and your cells do the work. And that's what's so cool about regenerative medicines. We're tapping back into your own natural biology. So for short, we call these stem cell derived exosomes. We call 'em just exosomes. When we refer to exosomes, we're really referring to the stem cell ones. Then aside from that, we have some even more fancier ones that have come up very recently. That's the natural killer cell derived exosomes? So it's a very, very small percentage of our system and it's part of our natural surveillance and security system. These cells go throughout the body. naturally kill, naturally remove abnormal cells that we're not supposed to have like cancer cells. And yes, during our lifetime we make accidental cancer cells, but this system removes them selectively and they never become a problem You reduce your ability to remove cells and then they, they win, they, They do not harm normal cells. They do not appear to have side effects, and this is an off the shelf kind of groundbreaking. either augmentative thing we can do for people for cancer care to help them with maybe stay in remission if they're at high risk, maybe they have a BRCA gene problem, maybe something they've had cancer, they wanna stay in remission, maybe they wanna bolster their immune system in between cycles. Maybe they're looking for a natural alternative and then. There is evidence, there is research that shows if you give NK cells natural killer cells for short or the exosomes, you can actually reduce the age related markers from the senescent cells, so it has potential for longevity assistance and Well, they're big pharma and the political arm that's kind of bought and sold by big pharma big implant companies. 'cause we do a lot of joint and spine care with regenerative medicine and people that sell metallic knee implants and spinal hardware don't want it out there. That there are lots of other options that'll significantly take a bite out of those income into those corporate incomes. I don't think that those, those, you know, the, the embryonic myth is that these come from aborted fetuses and things like that. There, there's actually nothing I've ever seen to support that. So our, our donor sources are highly regulated by the FDA. They go through a rigorous screening process. that could impact. So, this, this is a very, you know, regulated and proper process. It is moral, it is ethical, and anything you might hear to the contrary is again, part of that, narrative that certain people don't want this to flourish at the rate it seems to be flourishing. And I had been communicating with different labs, seeing where we could. We could, you know, be the first to obtain them. So

Is it genetic? Is it environmental? Is it diet?

Dr. Jeff Gross: 0:16

So this is the smoldering pro oxidation, rusting of the body's cells and it damages them and it, it's really related to aging and perhaps why we age at different rates and why we are supposed to avoid, you know too many electromagnetic fields and things like that because that affects our stem cell activity, our regular cell activity, and in our natural killer cell activity also.

Dr. Supatra Tovar: 0:17

Why do you think that the majority of messaging out there in terms of cancer focuses on genetics? When we have really seen through science that it is epigenetically oriented. We still see this so often in the media that, you know, it's, oh, if you have you know, a mother with breast cancer, you should go ahead and you know, remove your breasts just in case this will be turned on when we know that something else has to turn the cancer on.

Dr. Jeff Gross: 0:18

Now we now have technology to change your genes, but we're learning more about it and how to do it safely. And it's, the regenerative medicine stuff, I think is, is more natural and probably easier to apply at this juncture than, you know, gene therapy for cancer. Although it's, it's coming and it's coming fast. Now, if you have some type of poor response or allergic response to other food items like gluten, then, then yes, if you have gluten in that setting, you are going to stimulate your inflammatory system. And then you'll have all these sort of, you know your activities are, your cell activities are in fighting that inflammation and not in normal maintenance and surveillance, which is really what you want. We need protein. We are carnivores, we are nitrogen based life forms, with a carbon exoskeleton. So we're not carbon based. We're really nitrogen based. Without nitrogen. I would agree with that. I think that's fair. I, I think this, you know, I've seen some of those studies and, and they do speak to the pro-inflammatory nature of protein in animals and animal meat, but some of those, some of those meat consumptions weren't controlled by where they got the meat and what type of meat.

Dr. Supatra Tovar: 0:22

a lack of mindfulness, those kinds of things. You know, not being in alignment with your circadian rhythm. All of that contributes to inflammation. So we should be looking at it on the whole, and certainly people want to try to avoid cancer they should really look at inflammation in general in their bodies, correct?

Dr. Jeff Gross: 0:23

So you gotta get rid of 'em any way you can. There are other ways to get rid of 'em. Just to be clear, you can fast. You can exercise. These are other ways. There are other supplements and nutrients that support their removal, other phytonutrients. But NK cells are, are notoriously good for removing these. both injected into solid tumors and just in the, in the fluid in the Petri dish or in the circulating blood of the animal,
