Q. What are the cells that build up bone?
Osteoblasts are cells responsible for the secretion and deposition of bone morphogenetic proteins (BMPs) into the extracellular matrix during bone formation.
Q. Do osteoclasts build bone?
Osteoclasts, derived from hematopoietic precursors, are responsible for bone resorption, whereas osteoblasts, from mesenchymal cells, are responsible for bone formation (see the images below). Therefore, any process that increases the rate of bone remodeling results in net bone loss over time.

Q. What type of bone cell is the main bone building cell?
Osteoblasts
There are three types of cells that contribute to bone homeostasis. Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells. An equilibrium between osteoblasts and osteoclasts maintains bone tissue.
Q. What cells become osteoblasts?
5.2. Osteoblasts originate from immature mesenchymal stem cells, which can also differentiate and give rise to chondrocytes, muscle, fat, ligament and tendon cells (Aubin and Triffitt, 2002). Mesenchymal stem cells undergo several transcription steps to form mature osteoblast cells.
Q. Do osteoblasts make osteoclasts?
These specialized proteins activate another type of cells called osteoclasts: The main function of osteoblasts in bone formation and maintaining bone tissue integrity and shape.
Q. In which type of bone tissue are osteoblasts and osteoclasts present?
Spongy bone tissue is composed of trabeculae and forms the inner part of all bones. Four types of cells compose bony tissue: osteocytes, osteoclasts, osteoprogenitor cells, and osteoblasts.
Q. What is an osteoblast cell?
OSTEOBLASTS are the cells that form new bone. They also come from the bone marrow and are related to structural cells. Osteoblasts work in teams to build bone. They produce new bone called “osteoid” which is made of bone collagen and other protein.
