A child doesn’t just change your schedule—they change your cells. We dive into the science and meaning of microchimerism, the extraordinary transfer of fetal cells into a mother’s body that can persist for decades and even integrate into the brain. With research showing that up to 6% of a mother’s brain DNA may come from her children, we explore what this living mosaic means for identity, healing, and the way connection shows up in everyday physiology.
Guided by Dr. Kylie’s clinical lens and personal story of loss and love, we unpack how these cells travel to the heart, lungs, liver, skin, and neural tissue, and what early evidence suggests about their role in tissue repair and immune boosting.
This episode blends clear science with real-life resonance, offering a grounded take on why motherhood can feel like a permanent rewrite at the deepest level. If you’ve ever sensed that love leaves a physical imprint, here’s the evidence that it does. Press play, reflect on what it means to carry someone with you. If this moved you, I'd be honored to have you 1- follow the show, 2- leave a review, and 3- pass it to a friend who could use a science-backed reminder that connection is biology. Thanks!
