Eating well, sleeping enough and exercising do not stop your body from aging. Your stem cells keep declining, and the repair work your body cannot keep up with slowly adds up.
On this episode of Stem Cell Talk, Dr. Yi Song talks with Brenda Mundt about why early prevention matters more than any single treatment. Dr. Song grew up in a family practicing both traditional Chinese medicine and Western medicine, and she explains the four types of stem cells, why embryonic and hematopoietic cells are not used for joint treatments, and why your own cells in your 60s or 70s are also in their 60s or 70s. She also covers why shoulder problems become so common after 40 and 50, and how acupuncture, herbal support, movement and stem cell therapy were combined in her mother's shoulder recovery.
Dr. Song frames longevity around six principles from traditional Chinese medicine: early prevention, treating the root cause, knowing your body's constitution, tending the body like a garden instead of a machine, living in rhythm with nature, and a holistic mix of therapies. She is clear that stem cell therapy is not a one-time fix, and shares her own knee treatment and her silent acid reflux as examples of aging that a healthy lifestyle alone did not prevent.
This is an educational conversation for anyone who wants to address joint pain and aging-related conditions early, before they become chronic.

Modern medicine studies each molecule and each receptor in isolation. The problem is that we understand less than one percent of what is actually happening inside a cell, so treating only the part we can measure leaves the rest of the picture untouched.
Dr. Yi Song, dual PhD in Pathology and Oriental Medicine, comes from seventeen generations of Chinese medicine practice and has treated patients in Boston for twenty five years. In this conversation she explains why she stopped seeing aging as inevitable, how a family history of type 2 diabetes can be modified rather than repeated, and why her mother reached 81 with normal A1C and no medication.
Dr. Song walks through her six principles of natural longevity: recognize your body's constitution, practice early prevention, treat the root cause, tend your body like a garden rather than a machine, follow the natural rhythm, and combine every approach in the proportion your body needs. She covers what DNA testing can and cannot tell you, why cold hands can signal trapped heat rather than a cold constitution, how long term stress drives autoimmune conditions like colitis, and why she treats stem cells as a jumpstart rather than a cure, supported by exosomes, peptides, and herbal formulas at her retreat near Medellin.
This is an educational conversation for anyone who wants to understand where their own predispositions sit, what early prevention actually looks like in practice, and how regenerative approaches may support the body's own repair rather than replace it.

What Stem Cells Actually Do for Your Body
Season 1 · Episode 11
Friday, July 17, 2026 • Duration 45:55
Most people wait until symptoms are severe before they act. By then, the imbalance behind the problem has often been building quietly for years.
Dr. Yi Song, raised in a 17-generation Chinese medical family and trained in pathology at Brown University, joins the Human Optimization Podcast to explain her six principles for natural longevity. She walks through why recognizing your body's constitution, addressing imbalances early, and treating the root cause matter more than chasing one symptom at a time. She uses her own family as an example, including how her mother reached 81 without diabetes or medication despite a strong family history.
Dr. Song also shares how she brought umbilical cord stem cell therapy into her practice after it helped calm her mother's chronic leg inflammation, and why she views stem cells as a jump start for the body's own regeneration rather than a magic fix. She covers who may be a candidate, what the consultation and process involve, and how stem cell therapy can be combined with acupuncture, herbal medicine, red light, and other supportive therapies when appropriate.
This is an educational conversation for anyone exploring how traditional Chinese medicine and regenerative approaches may support healthier aging and a longer health span.

Cord Banking, Botox, and Aging Powerfully: What the Wellness Industry Gets Wrong
Season 1 · Episode 8
Friday, May 8, 2026 • Duration 59:31
Most women hear about stem cells, exosomes, and cord banking without anyone explaining what is actually happening at the cellular level. The science is more nuanced, and the marketing often is not.
In this conversation on Stem Cell Talk, Dr. Yi Song breaks down the four types of stem cells, why only mesenchymal stem cells from the umbilical cord are used in her practice, and why this category does not behave like the embryonic or pluripotent cells most people associate with risk. She explains why stem cells do not replace tissue but instead act as a jump start that wakes up the body's own repair systems through growth factors and exosomes.
The discussion moves through the topics women actually ask about: cord blood banking and why most current protocols leave families unable to use what they paid to store, autoimmune treatment with intravenous infusions, fertility and uterine repair, premature ovarian atrophy, and the experimental use of stem cells for hearing, optic nerve, and cerebrospinal procedures. Dr. Yi Song also explains how she approaches aging powerfully without relying on Botox or fillers, including microneedling with stem cells and PRP, biological filler with PRF, exosome nasal spray for brain health, and the role of facial acupuncture and Cacay oil as gentler entry points.
The conversation closes on the future of regenerative medicine for women, including menopause, severe osteoporosis, hair regrowth, and how NAD and mitochondrial support fit into a whole body strategy that respects both modern science and traditional Chinese medicine.
If you are exploring stem cell therapy, autoimmune support, or alternatives to conventional anti-aging, this episode offers a grounded perspective on what these tools can and cannot do.

Stem Cell Therapy Explained: What Really Happens After Injection
Season 1 · Episode 7
Friday, April 17, 2026 • Duration 50:22
What if stem cells don’t actually “heal” you the way most people think?
In this conversation with former professional baseball player, coach, and current television sports color commentator Eduardo Pérez. Dr. Yi breaks down what truly happens after stem cell therapy, from the moment cells enter the body to how they signal your own repair system to respond. Instead of acting as a direct fix, stem cells release growth factors and signaling molecules that guide your body to reduce inflammation and begin repair where it is needed most.
You will hear a real patient experience just days after treatment, including what recovery actually feels like, why soreness is expected early on, and how improvement unfolds over time. The discussion also explores how stem cells locate inflammation, how long they remain active in the body, and why the number of cells used can influence outcomes.
Beyond the procedure itself, this episode connects modern regenerative science with a broader, holistic approach. Topics include anti inflammatory nutrition, red light therapy, and the role of chronic inflammation in aging and pain. Dr. Yi also explains why combining therapies and understanding your unique body can make a meaningful difference in long term results.
If you are considering stem cell therapy or simply want a clearer, science grounded perspective, this episode offers a practical and honest look at what to expect.

Stem Cell Therapy for Athletes: MLB Veteran Eduardo Pérez Shares His Recovery Story
Friday, April 10, 2026 • Duration 37:59
What happens when a professional athlete with 17 surgeries starts questioning the traditional path of painkillers and repeated operations?
In this conversation, former Major League Baseball player and ESPN baseball commentator Eddie Perez shares his personal journey through decades of sports injuries and recovery. After years of knee surgeries, shoulder issues, and chronic inflammation from professional athletics, he began exploring regenerative approaches such as stem cell therapy. He describes his early experience using his own stem cells for shoulder injuries, and later trying umbilical cord stem cell treatment after another knee surgery did not fully resolve the problem.
The discussion explores how athletes manage the physical toll of high-level performance and why recovery strategies matter just as much as training. Eddie also reflects on the culture of professional sports, where players often push through pain to stay on the field, and how regenerative medicine could potentially change the way athletes approach injury recovery and long-term joint health.
Dr. Yi Song explains how stem cell therapy may support tissue repair, reduce inflammation, and help the body recover more effectively when used as part of a broader strategy that includes rest, rehabilitation, and proper training.
The conversation also addresses common concerns athletes have about stem cell treatments, including regulation, safety, and whether these therapies could affect drug testing in professional sports.
For athletes, trainers, and anyone dealing with chronic joint pain or sports injuries, this discussion provides a grounded look at how regenerative medicine is being explored in the real world.

Why Stem Cell Therapy Treats the Root Cause, Not Just Symptoms
Season 1 · Episode 5
Friday, April 10, 2026 • Duration 30:37
Most treatments manage symptoms. Few address why the body stopped healing in the first place.
In this conversation, Dr. Yi Song explains how stem cell therapy aligns with the same root-cause principles found in traditional Chinese medicine, and why regeneration requires more than pain relief or temporary suppression of inflammation. Drawing from her background in pathology, acupuncture, and regenerative medicine, Dr. Song shares how stem cells support the body’s innate repair systems, when they are appropriate, when caution is required, and why chronic inflammation plays such a central role in aging and disease.
The discussion also explores real clinical experiences, including vascular inflammation, joint degeneration, autoimmune conditions, and neurological challenges. Dr. Song explains how patient constitution, emotional stress, immune balance, and treatment timing all influence outcomes. This is an educational conversation for those who are curious but skeptical, and who want a deeper understanding of how regenerative medicine fits into a whole-body approach to healing.
