Stage Time

Unfertilized oocyte Before fertilization

Fertilized oocyte (zygote) Time 0

2-cell stage 30 h after fertilization

4-cell stage 40-45 h after fertilization

8-cell stage 65-70 h after fertilization

16-cell stage (morula) 96 h after fertilization

Blastula Blastocyst Just prior to implantation. Differentiation starts here.

Fertilization (aka syngamy) joining of parental gametes (oocyte & spermatozoa) to form a zygote (single-celled stage).

Creation and development of an embryo after fertilization

Example of Cell Differentiation:

Hematopoieticstem cells are for“Blood production”

“hemato” = blood“poieo” = create, make
