Template talk:Embryonic Spleen Timeline Table

Embryonic Carnegie stage data from a recent study of the Kyoto Collection embryos. Carnegie stage 13 - spleen neither a bulge nor as a high-density area Carnegie stage 14 to 17 - spleen a bulge in the dorsal mesogastrium. Carnegie stage 14 - dorsal mesogastrium vessels. Carnegie stage 16 to 18 - A high-density area was first recognized. Carnegie stage 16 - pseudostratified mesothelium replaced with high columnar cells and then with low columnar cells. Carnegie stage 17 - basement membrane was obvious. Carnegie stage 18 - haematopoietic cells were detected. Carnegie stage 19 and 23 - spleen and stomach increase in length at the same rate (0.51 ± 0.11). Carnegie stage 20 - after this stage the spleen became apparent (Intrasplenic folds occur later). dorsal mesogastrium cells differentiated into mesenchymal cells and sinus formation started. hilus formation. Carnegie stage 23 - parallel entry of the arteries and veins. Kyoto Collection
