Proteoglycan production was examined in cultures of thioglycollate-elicited peritoneal macrophages obtained from White Carneau and Show Racer pigeons. Following a 24-h incubation in the presence of [35S]sulfate and [3H]serine, total production and distribution of 35S-labeled proteoglycan into media (60-65%), pericellular (21-27%), and intracellular (13-14%) compartments was similar in White Carneau and Show Racer macrophage cultures. Media proteoglycans consisted of high-molecular-weight chondroitin sulfate proteoglycan, low-molecular-weight chondroitin sulfate proteoglycan, and heparan sulfate proteoglycan. High-molecular-weight chondroitin sulfate proteoglycan was predominantly 6-sulfated (80%) and contained a core protein larger than 200 kd, whereas low-molecular-weight chondroitin sulfate proteoglycan was 4-sulfated and contained a 28-kd core protein. Pericellular proteoglycan was similar in size to low-molecular-weight proteoglycan and consisted of a predominantly 6-sulfated (75%) chondroitin sulfate proteoglycan and heparan sulfate proteoglycan. Intracellular 35S-labeled chondroitin sulfate and heparan sulfate were smaller than media and pericellular proteoglycans, suggestive of intracellular degradative processing.

UI	MeSH Term	Description	Entries
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D010529	Peritoneal Cavity	The space enclosed by the peritoneum. It is divided into two portions, the greater sac and the lesser sac or omental bursa, which lies behind the STOMACH. The two sacs are connected by the foramen of Winslow, or epiploic foramen.	Greater Sac,Lesser Sac,Omental Bursa,Bursa, Omental,Cavity, Peritoneal,Sac, Greater,Sac, Lesser
D010856	Columbidae	Family in the order COLUMBIFORMES, comprised of pigeons or doves. They are BIRDS with short legs, stout bodies, small heads, and slender bills. Some sources call the smaller species doves and the larger pigeons, but the names are interchangeable.
