SC synchronization

I was recently speaking with a colleague of mine that mentioned a phenomenon that he was studying in plant cells that he called synchronization. The cells, when submitted to certain stress factors seems to counter the disturbance by somehow communicating with each other stabilizing to the new state.
I’ve recently fell in love with stem cell research and had a thought come across my mind, does such “synchronization” happen in stem cells when they are presented to external stimuli (ex: diferenciation factors)?
Does the response of the SC cluster happen on an individual level or is there communication between the SCs?
Sorry if my question is not properly formulated, but hopefully the message makes it across.

Yes, Ricardo, this is pretty much how ‘in vitro’ differentiation occurs. One cell will reach a tipping point in signal and the stimuli will propagate outwards. Of course, there’s feed-forward and -back regulation, so you get more of a patterning than a synchronization phenomenon.

Thank you for the reply and specially for the link!

i’ve recently started taking stem-enhance its an all natural suplmnt. that contains 1000mg of afa. aphanizomenon-flos-aquae extract which support therelease and migration of stem cells in the body. i have several health related illnesses, i am on the waiting list at UCLA for a livertransplant, i also have a-fibas well as having two tricuspid replacements, hep c and copd. since i started taking this as well as cayenne pepper cell-food, and another product called crystal mana(which also contains a.f.a) my blood work has stablized my liver functions have improved and i feel much better because of this.the supplmnt was developed by a dr in montreal his name is Christian Drapeu. you can learn more about the research and developement by watching an 8 minute video on www.changedirection.stemtechbiz.com i think you will find it very informative….peace
