Streeter 3 divided the human embryonal period into 23 developmental horizons, and his classification is the basis of the Carnegie staging system of human prenatal development. 4. The Streeter term “horizon” was replaced in the newer classifications by the old term “stage” (used first by Mall 5 in 1914). Each stage is characterized by defined external and internal features.
Unlike other types of stem cells, these were ‘pluripotent’ – meaning they had the potential to generate any type of body tissue if given the right signals. For many this news, and the accompanying cla.
Human embryonic kidney 293 cells, also often referred to as HEK 293, HEK-293, 293 cells, or less precisely as HEK cells, are a specific cell line originally derived from human embryonic kidney cells grown in tissue culture.HEK 293 cells have been widely used in cell biology research for many years, because of their reliable growth and propensity for transfection.
BRANCHES OF BIOLOGY. Anatomy — It is a branch of biology which deals with the study of internal structure of an organism as revealed by dissection. Arthrology — Study of joints.

Animal development – Embryonic induction: The organization of the embryo as a whole appears to be determined to a large extent during gastrulation, by which process different regions of the blastoderm are displaced and brought into new spatial relationships to each other. Groups of cells that were distant from each other in the blastula come into close contact, which increases possibilities.
