Solution

The cells that form ossification centers are osteoblasts. Here's a step-by-step explanation:

  1. Ossification, or bone formation, occurs in specific areas called ossification centers.

  2. This process begins when mesenchymal stem cells differentiate into osteoblasts, which are the bone-forming cells.

  3. Osteoblasts secrete an extracellular matrix that forms the initial bone tissue. This tissue is not yet fully hardened, which allows for the formation of blood vessels and further growth.

  4. As the osteoblasts continue to secrete bone tissue, they become trapped in the matrix and differentiate into osteocytes, the most common type of bone cell. These cells maintain the bone tissue.

  5. Osteoclasts are involved in bone remodeling, or the process of resorption and formation of bone that happens throughout life. They break down bone tissue, which allows osteoblasts to form new bone in those areas.

So, in the context of your question, the correct answer is b. Osteoblasts. They are the cells that form the initial bone tissue at ossification centers.
