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.
