Motor proteins, such as myosin Va, transport vesicle cargos along Factin. Defective myosin Va is the cause of Griscelli syndrome, a
disorder in the transport of melanosomes from melanocytes to
keratinocytes in the epidermis. Patients with Griscelli syndro
The position and stability of the epithelial cell layer are maintained by
cell adhesion molecules and cell junctions.
Cell adhesion molecules can be classified as Ca2+-dependent and
Ca2+-independent. Cadherins and selectins are Ca2+-dep
Essential concepts | Epithelium
Epithelium is one of the four basic tissues. The three additional basic
tissues are connective tissue, muscle tissue, and nervous tissue.
Epithelia can be classified into three m
Keep In mind that not only fibroblasts can produce collagens.
Osteoblasts, chondroblasts, odontoblasts, and smooth muscle cells can
also synthesize collagens. Even epithelial cells can synthesize type IV
collagen. You have already seen th
Membrane proteins tend to remain associated to the cytoplasmic or
protoplasmic leaflet and appear as particles in on the P fracture face
(PF). Pits complementary to the particles and representing the space
once occupied by the protein, are present on the

Smooth muscle cells are found in the wall of the alimentary tube,
urinary excretory passages, respiratory tract, uterus, and blood vessels.
Smooth muscle cells are spindle-shaped, tapering cells, with a central
nucleus and surrounded by
There are two types of agranulocytes: lymphocytes and monocytes.
Lymphocytes are either large lymphocytes (9 to 12 m in diameter) or
small lymphocytes (6 to 8 m in diameter). Lymphocytes are divided
