CD 34
HEMATOPOIESIS CONSIDERED TO START AROUND THE ____
19TH DAY OF EMBRYONIC DEVELOPMENT AFTER FERTILIZATION
MOST WIDELY ACCEPTED THEORY AMONG EXPERIMENTAL HEMATOLOGIST
MONOPHYLETIC THEORY
SUGGESTS THAT EACH OF THE BLOOD CELL LINEAGES IS DERIVED FROM ITS OWN UNIQUE. STEM CELL
POLYPHYLETIC THEORY
SUGGEST THAT ALL BLOOD CELLS ARE DERIVED FROM A SINGLE PROGENITOR STEM CELL
MONOPHYLETIC THEORY
