hello, i am researching how the hematopoietic stem cells found in umbilical cord blood differentiate, i understand the replication side of things but would appreciate it if someone would give me a practical example of how the internal (genes in DNA)and external(chemicals excreted from cells within microenvironment) factors contribute to differentiation in any instance. If someone could do an example with liver or bone marrow it would be exceelent
