Detailed explanation-1: -Yellow: Yellow bone marrow stores fat. There are two types of stem cells in yellow bone marrow (adipocytes and mesenchymal stem cells). These cells preserve fat for energy production and develop bone, cartilage, muscles and fat cells for your body.

Detailed explanation-2: -The fats in yellow bone marrow are stored in cells called adipocytes. This fat can be used as an energy source when needed. Yellow bone marrow also contains mesenchymal stem cells. These are cells that can develop into bone, fat, cartilage, or muscle cells.

Detailed explanation-3: -Bone marrow fat (BMF) is located in the bone marrow cavity and accounts for 70% of adult bone marrow volume. It also accounts for approximately 10% of total fat in healthy adults above the age of 25 years (1, 2).

Detailed explanation-4: -The yellow color of these bone marrows is due to the presence of carotenoid in the tissue’s fat droplets. In special conditions where blood is lost, it converts into red bone marrow in order to facilitate the production of blood cells.

Detailed explanation-5: -Bone marrow adipose tissue (BMAT), sometimes referred to as marrow adipose tissue (MAT), is a type of fat deposit in bone marrow.
