Cell Differentiation Question!!!

Post by Lily786 » Mon Mar 13, 2006 2:07 am

Hi everyone, here is my question...

At what point in time in a pregnancy (in terms of days, weeks) do embryonic cells start to differentiate into particular organ or tissue cells?

Any answers or suggestions are greatly appreciated. Thanks!

While i don't have a definite answer for you, i can tell you this: very early. By the 4th week of preganancy bones start to form, so i would say that tissues start to develop in the first 2-4 weeks
