What is the Role of Alveolar Macrophages in the Lungs?
Alveolar macrophages in the lungs are specialised cells that are present in the epithelial surface of alveoli. This is the site where gaseous exchange is facilitated. These macrophages serve as the first line of defence in the respiratory system. These cells conduct surveillance of inhaled air for pRead more
Alveolar macrophages in the lungs are specialised cells that are present in the epithelial surface of alveoli. This is the site where gaseous exchange is facilitated. These macrophages serve as the first line of defence in the respiratory system. These cells conduct surveillance of inhaled air for pathogens, allergens, particulate matter and environmental pollutants.
See lessIt is involved in phagocytosis of foreign particles- the process of engulfing and digestion of microorganisms, debris and dead cells. It efficiently clears bacteria, viruses, fungal spores, and particulate matter. Alveolar macrophages further maintain sterility in the lower respiratory tract and further prevent infection.
What are the Roles of Osteoblasts and Osteoclasts?
Osteoblasts and osteoclasts are two distinct types of bone cells that work together to maintain healthy bones through bone remodeling. Both osteoblast and osteoclast have distinct roles as follows: Osteoblasts are known as bone-building cells. These cells are responsible for new bone tissue formatioRead more
Osteoblasts and osteoclasts are two distinct types of bone cells that work together to maintain healthy bones through bone remodeling. Both osteoblast and osteoclast have distinct roles as follows:
See lessOsteoblasts are known as bone-building cells. These cells are responsible for new bone tissue formation. These cells are responsible for synthesizing collagen and other proteins, and are responsible for creating bone matrices. This helps in the deposition of calcium and phosphate. This process strengthens bones and supports growth, healing, and repair after injuries or fractures. Once osteoblasts complete their work, some become osteocytes (mature bone cells), while others die or remain inactive.
Main functions of osteoblasts:
Build new bone
Produce bone matrix
Promote mineralization

Bone marrow stem cell therapy is globally emerging as a significant regenerative medicine approach. In Malaysia, the therapy is applied in various s like cases tissue degeneration, immune dysfunction, and bone or joint disorders. Bone marrow consists of mesenchymal stem cells (MSCs) and hematopoietic stem cells (HSCs). These stem cells possess the ability to support tissue repair, reduce inflammation, and modulate immune responses — key mechanisms in regenerative care.
See lessDoes Bone Marrow Contain Stem Cells?
Yes, bone marrow consists of stem cells. Bone marrow in humans is among the most important sites where stem cells are present. It is a soft, spongy structure present inside the long bone particularly in the spine, hip, ribs, and long bones. It serves as a crucial site for blood formation and plays aRead more
Yes, bone marrow consists of stem cells. Bone marrow in humans is among the most important sites where stem cells are present. It is a soft, spongy structure present inside the long bone particularly in the spine, hip, ribs, and long bones. It serves as a crucial site for blood formation and plays a vital role in the tissue repair mechanisms of the body. Bone marrow plays a critical role in one’s immune function due to the presence of a specialized stem cell population.
