Changing Places

Bone marrow not only replenishes our blood, it’s also a source of stem cells for our tissues. Stem cells are a biological ’blank slate’ with the potential to mature into any type of cell. How they travel to different organs and adopt a specialized function remains a hotly-pursued research goal. Transplanting bone marrow from a mouse with green fluorescent protein (GFP) in its cells into a mouse that lacks bone marrow reveals where these cells are going. Fluorescent green cells in this pancreas have originated from the bone marrow. And they are fit for purpose, producing pancreatic enzymes. This experiment helped the resesarchers establish that bone marrow cells migrate to the pancreas and become cancer stroma (non-cancerous cells which ’help’ pancreatic cancer cells grow) altering the response to treatment. Using animal models like this helps explain how cells travel between organs, which is relevant to new cancer treatments.
