A short talk/transcript excerpt about how exosomes and peptides (notably epithalin) influence stem cell fate and promote neurogenesis. The speaker describes a study using human buccal (mouth) cavity-derived stem cells in vitro where epithalin activated multiple genes (~4–5) to drive neuron formation, and emphasizes the role of environment and signaling in directing stem cells toward neuronal versus other lineages.

Questions this video answers

Buccal (mouth) cavity (human).

Epithalin.

Approximately four to five genes (speaker said 'five, four or five different genes').

So exosomes are the really magical part of regeneration. So I know we have peptides that can. If you have epithalin with mesocharmic stem cells. There's a study that was published that shows that using human stem cells from. From men, from their mouth cavity, the buccal cavity, and then put in a Petri dish and then use epithalin, they grew new neurons because it turns on five, four or five different genes to make a certain protein, and those proteins are needed for. For basically neurogenesis. So you need the right environment for the stem cells to convert. So how do you know the stem cells can convert to a heart cell or to a neuron? Epithalin seems to turn it into brain cells, which is brain cells. They can kind of target it that way or, you know, guide it that way, if you will.
