Answer:
Osteochondral Progenitor cells
Explanation:
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.
Answer:
The nucleus contains nearly all of the cell's DNA, surrounded by a network of fibrous intermediate filaments and enveloped in a double membrane called the "nuclear envelope". The nuclear envelope separates the fluid inside the nucleus, called the nucleoplasm, from the rest of the cell.
