Well, hello, hello, guys, you're listening to Beauty Bites with Dr. K., Secrets of a Plastic Surgeon,

and it's time for a five-minute Friday. So let's talk

all about stem cell growth factors. And this is such an exciting topic. You guys have all

heard of stem cells. You may have heard of stem cell growth factors, but I want to explain to you

why they are so important and such a great ingredient to include

in your skin care regimen. So growth factors have been around for a long time, first discovered

in the 1980s by Dr. Rita Mantalachini and Dr. Stanley Cohen, who were awarded the Nobel Prize

in physiology for studying these epidermal growth

factors. But their research has had such major impact in our understanding of human

cellular reproduction and growth. If you need to know more about growth factors, we start back

there in the 80s with the understanding that stem cells are foundational cells. These are

cells that are found within our regenerative systems of the body like our bone marrow,

our spleen. And these are the cells that are going to differentiate from one pluripotent

cell into multiple different cells all throughout your body.

Stem cells communicate with each other by producing and releasing proteins called cytokines and

growth factors.

And when they're grown in a laboratory sitting in a plate, a petri dish, they're going to

make this wonderful brew sort of like a juicy nutrient broth that comes

from their living together and growing up and excreting certain cytokines and factors.

When these growth factors are released, they can bind to cells and cell membranes

and trigger all these amazing activation pathways that tell your

superficial tissues of your skin to wake up and start behaving more youthfully.
