These cells are often called erythroid/myeloid … WebThe early production of erythroid lineage cells occurs in the yolk sac, a transient extraembryonic tissue. These erythroid cells are nucleated and short-lived. They are derived from mesodermal cells that are formed from epiblast cells ingressing through the primitive streak ( Lawson et al. 1991; Kinder et al. 1999 ).
