The path from stem cell to mature adult cell is not a one-way street

Developing bone in normal (top) and mutant (bottom) embryos. Protrusions in a developing bone are formed by a distinct class of cells (green) that differ from the regular bone-forming cells (yellow-orange). Incorrect regulation and distribution of these cells leads to irregularities in the shape of the forming bone

Scientists isolate new human pluripotent stem cells capable of generating “humanized” mouse models containing human-derived tissues

Left column: Previous method for creating induced pluripotent stem cells (iPSCs); right column: iPSCs produced with the new method developed by Dr. Hanna. Top: Skin cells (red); center: iPSCs from skin cells (green); bottom: superimposed top and center images. Skin cells that have been reprogrammed into iPSCs appear light yellow. Only a small percentage of the cells on the left have been reprogrammed, in contrast with the high success rate seen with the new method on the right

Future stem cell therapies might depend on our ability to chose those that won’t turn cancerous

Prostaglandins guard stem cells by increasing the production of an inhibitory factor in the mesenchymal bone marrow cells. Mesenchymal cells are marked with a green protein (left); the inhibitory factor is red (center). Combined image (right): Treatment with prostaglandins (bottom) increases the secretion of the inhibitory factor
