Cells that can build bony matrix.
A
Osteoblasts
B
Osteoclasts
C
Canaliculi
D
Lamellae
Explanation: 

Detailed explanation-1: -Osteoblasts are derived from mesenchymal stem cells (MSC). The commitment of MSC towards the osteoprogenitor lineage requires the expression of specific genes, following timely programmed steps, including the synthesis of bone morphogenetic proteins (BMPs) and members of the Wingless (Wnt) pathways [25].

Detailed explanation-2: -Osteoblasts are colloquially referred to as cells that “build” bone. Bone is approximately 10% water, 30% organic, and 60% inorganic. Osteoblasts derive from two embryonic populations of mesenchymal stromal cells (or mesenchymal stem cells, MSCs).
