Robert Hooke Dicovers First Cell
He Saw Cork cells under a microscope at 50x he discribed them as pores or cells stuck together by a wall -
Anton van Leeuwenhoek
Looked at cells through a simple microscope -
First Stem cell discovered in human cord blood
an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. -
First in vitro stem cell line developed from mice
-
Embryonic stem cell lines created from a hamster.
Embryonic stem cells (ES cells) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage preimplantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells. -

Stem Cells Can be made.
Scientists in Japan showed stem cells can now be made quickly just by dipping blood cells into acid. -
One of the X Chromosomes in women are inactive
In female mammals, one of the two X chromosomes is inactivated. Thanks to research using special stem cells, geneticists have been able to provide detailed insight into the molecular mechanism behind this inactivation process. -
Embryonic stem cells controlled with light
Researchers have for the first time developed a method to precisely control embryonic stem cell differentiation with beams of light, enabling them to be transformed into neurons in response to a precise external cue.
