Osteochondral Progenitor cells are cells that can form a specific type of tissue. These cells form cells that can give rise to the bone and its components, especially fibers. These Progenitor cells originate from the mesenchymal stem cells.
The cells which form the bone are known as the osteoblasts and the cell which forms the fiber is known as the chondroblasts.
Thus, Osteochondral Progenitor cells is correct.

Exocytosis: Exocytosis can be described as a form of active transport in which molecules move out of a cell.
Endocytosis: Endocytosis can be described as a process which utilizes ATP to transport molecules inside a cell.
