Here we present a protocol for the dissection of hind limb long bones (femurs and tibiae) from the laboratory mouse. We further describe a rapid technique for bone marrow isolation from these bones that utilizes centrifugation for removal of bone marrow from the bone marrow space.

Bone Cells and Tissue

Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts. Osteoblasts and Osteocytes The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the periosteum and...

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it. Hormones That Influence Osteoblasts and/or Maintain the Matrix Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Here we describe an optimized, highly reproducible protocol to isolate Mesodermal Progenitor Cells (MPCs) from human bone marrow (hBM). MPCs were characterized by flow cytometry and nestin expression. They showed the ability to give rise to exponentially growing MSC-like cell cultures while retaining their angiogenic potential.
FAQs
Mechanical fragmentation reduces developing skeletal elements into smaller pieces, while enzymatic digestion helps release resident cells from the surrounding matrix. The balance between these steps depends on whether the experiment requires dispersed cells for culture and molecular assays or intact tissue architecture for histology and imaging. Choosing appropriately preserves the information most relevant to the study.
Removing attached soft tissue helps enrich the sample for the skeletal element and its associated cells or matrix. This step reduces unwanted surrounding material that could complicate histology, imaging, gene-expression measurements, or cell-based analyses. Consistent dissection and cleaning also improve sample quality, making results more comparable between specimens and developmental stages.
Isolated samples can reveal how osteoblasts and chondrocytes differentiate, how skeletal tissues mineralize, and how gene expression and signaling change during development. Because isolation provides access at tissue, cellular, and molecular levels, the same general approach can support complementary analyses rather than limiting investigation to one layer of skeletal development.
A typical workflow begins by dissecting the developing skeletal element, followed by removal of attached soft tissue. The specimen is then mechanically fragmented, with enzymatic digestion added when cell release is required. The resulting material can be directed toward tissue-preserving analyses or dispersed-cell studies, depending on whether architecture or cellular access is the priority.
The downstream question determines the isolation strategy. Preserving tissue architecture is appropriate when histology or imaging must show spatial organization within the developing element. Mechanical fragmentation with enzymatic digestion is more suitable when researchers need released cells for culture or molecular assays. This choice affects which structural, cellular, or molecular outcomes remain measurable.
Standardized isolation provides a consistent starting material for examining developmental changes. Researchers can compare osteoblast or chondrocyte differentiation, mineralization, gene expression, and signaling across stages while reducing variation caused by inconsistent dissection or tissue handling. These comparisons help relate observed molecular or cellular differences to skeletal development rather than to differences in sample preparation.
