Who am I? How cells find their identity. A research group has investigated more closely how a single embryonic cell develops into a heart, nerve or blood cell. For the first time, the researchers have been able to reconstruct the developmental trajectories of individual embryonic cells. Their results also suggest that cells can change their path during their maturation process. Source 5q.
I believe that the RNA of the cells will tell them what to become and it is all in the DNA sequencing too. A T cell can be with other cells around it to determine what special cell to become I believe that makes them so flexible. I know it has been a long time since I studied cells and their functions but I do believe it has a lot to the RNA sequences.
