Bone Marrow: The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

Tissue Regeneration with Somatic Stem Cells

JoVE 5339

Somatic or adult stem cells, like embryonic stem cells, are capable of self-renewal but demonstrate a restricted differentiation potential. Nonetheless, these cells are crucial to homeostatic processes and play an important role in tissue repair. By studying and manipulating this cell population, scientist may be able to develop new regenerative therapies for injuries and diseases.

This video first defines somatic stem cells, and then explores the role these cells play in tissue regeneration. This is emphasized in a description of a protocol that isolates muscle satellite cells and uses them to repair muscle damage in a mouse model of muscular dystrophy. Finally, we discuss specific tissue regeneration studies utilizing somatic stem cells.

An Introduction to Stem Cell Biology

JoVE 5331

Cells that can differentiate into a variety of cell types, known as stem cells, are at the center of one of the most exciting fields of science today. Stem cell biologists are working to understand the basic mechanisms that regulate how these cells function. These researchers are also interested in harnessing the remarkable potential of stem cells to treat human diseases.

Here, JoVE presents an introduction to the captivating world of stem cell biology. We begin with a timeline of landmark studies, from the first experimental evidence for hematopoietic stem cells in the 1960s, to more recent breakthroughs like induced pluripotent stem cells. Next, key questions about stem cell biology are introduced, for example: How do these cells maintain their unique ability to undergo self-renewal? This is followed by a discussion of some prominent methods used to answer these questions. Finally, several experiments are presented to demonstrate the use of stem cells in regenerative medicine.

Whole Organ Tissue Culture

JoVE 5799

Whole organs can be cultured ex vivo using specialized bioreactors, with the goal of repairing or replacing entire organs. This method uses a donor organ that is stripped of all cells, leaving behind the three-dimensional structure, and is then repopulated with new cells. This video demonstrates the whole organ culture of lungs, and shows how a dynamic culture that mimics the mechanical stimulation in the body is needed to induce native tissue properties.
