Specialized Cells

Differentiation: Cells specialize to perform specific functions, turning on specific genes and turning off others.
Skin Cells: Outer layer of skin, protection from environment, reduces water loss.
Bone Cells: Collect calcium, allow growth and repair of bones, build bone around themselves.
Fat Cells: Have large vacuoles to store fat (chemical energy).
Skeletal Muscle Cells: Arranged in bundles called muscle fibers, contract and relax to move bones.
Cardiac Muscle Cells: Beat continuously, contract and conduct electrical impulses without nerve stimulation.
Red Blood Cells: Transport oxygen and carbon dioxide throughout the body.
White Blood Cells: Ameoboid cells, engulf bacteria and fight infection.
Sperm Cells: Have flagella for swimming, carry male DNA to join with female DNA (egg).
Nerve Cells (Neurons): Long, thin, branched, conduct electrical impulses to coordinate body activity.

Stem Cells

Undifferentiated Cells: Divide to form specialized cells.
Embryonic Stem Cells: Can differentiate into any kind of cell.
Tissue Stem Cells: Adult cells within specialized tissues, can only differentiate into certain cell types (e.g., bone marrow cells).
Cord Blood Banking: Collects stem cells from umbilical cord blood, potential for treating various diseases.
