Another form of adipose tissue is known as brown fat or brown adipose tissue (BAT) located mainly around the neck and large blood vessels of …
As with all hematopoietic lineages, T cells originate from self-renewing hematopoietic stem cells that reside in the bone marrow during steady-state postnatal life. However, unlike other major lineages, commitment to a specific T-cell program does not occur in the marrow, but rather begins only after seeding of …The primary center of ossification is the area where bone growth occurs between the periosteum and the bone. Osteogenic cells that originate from the periosteum increase appositional growth and a bone collar is formed. The bone collar is eventually mineralized and lamellar bone is formed.
