What type of cells are osteocytes?

Osteocytes are specialized cells that are embedded within the bone matrix and play a crucial role in maintaining bone tissue. They originate from osteoblasts, which are the cells responsible for bone formation. Once osteoblasts create new bone matrix and become entrapped in it, they differentiate into osteocytes.

These cells are fundamental to the bone's overall health as they help regulate mineral content, signal to other bone cells regarding tissue maintenance, and respond to mechanical stress by coordinating the activity of osteoblasts and osteoclasts. This interaction helps ensure that bone remains strong and adapts to the stresses placed upon it.

In contrast, the other options refer to different cell types that serve specific functions in the body. For example, cells that transport nutrients would pertain to blood cells like red blood cells, while cells that form cartilage are chondrocytes. The cells that create blood, such as hematopoietic stem cells, are found in the bone marrow and are distinctly different from osteocytes.
