-
indigenous cells
born, live, and die in connective tissue
-
chondrocytes
responsible for making cartilage
-
osteoblasts
produce bone material
-
fibroblasts
specialized cell job is to produce most of extracellular matrix between most tissues
-
most common type of fat cell
white fat cells-adipose tissue
-
composition of fat cells
big lipid droplet filled with triglycerides
-
half life of a white fat cell
10 years
-
what is leptin
- a peptide hormone produced by white fat cells
- represses appetite
-
common mutation in people who are clinically obese
have mutations in leptin signaling
-
what happens if a non-leptin deficient person takes leptin pill to lose weight
nothing
-
composition of brown fat cell
a lot of mitochondria and fat droplets
-
what type of fat do hibernating animals have
brown fat - releases heat
-
what two types of cells have the same developmental origin
muscle and brown fat cells
-
difference in brown fat between babies and adults
babies have more to keep warm while adults have less
-
beige fat cells
behave similar to brown but has less mitos and has developmental origin as white fat cells
-
protein involved with heat production in the cell
uncoupling protein- allows H+ to move from intermembrane space to matrix
-
protein with similar function of uncoupling protein
2,4- dinitrophenol look up
-
base of blood cells
hematopoetic stem cells in bone marrow
-
differentiation of hematopoetic stem cells
lymphatic or myleoid
-
what governs differentiation of stem cells in bone marrow
different environments in the marrow, has different growth factors
-
differentiation of lymphatic stem cells
B or T cells
-
differentiation of myeloid cells
granular/monocytes or megakaryocyte/RBC
-
example of a granulocyte
neutrophil
-
life span of neutrophil
1 day
-
characteristics of granulocyte
contains secretory granules, small cells, highly motile, professional phagocytes
-
example of monocytes
macrophages - large cells also phagocytic
-
characteristics of macrophages
- large cells, less motile, crawl to tissues and are permanent residents
- ex: osteoblasts
-
characteristics of megakaryote
large multinucleate cell that produce platelets
-
function/characteristics of platelets
no nucleus, buds off and regulate clotting
-
Red blood cell characteristics
- caries O2
- bag of hemoglobin
- they last for 4 months
