I will praise thee; for I am fearfully and wonderfully made... Psalm 139:14
"A research team led by University of California, Los Angeles
scientists has created a single-cell transcriptome map of human
hematopoietic tissues from the first trimester to birth.
Blood stem cells, or hematopoietic stem cells, have the ability to make unlimited copies of themselves and to differentiate into every type of blood cell in the human body.
---....the map unveils specific milestones in their maturation process,
including their arrival in the liver, where they acquire the special
abilities of blood stem cells.
---The researchers also pinpointed the exact precursor in the blood vessel wall that gives rise to blood stem cells."
