✯ Nerve cells and glial cells, coloured scanning electron micrograph (SEM). The nerve cells have small cell bodies (orange) and fine extensions called axons and dendrites (brown). The glial cells have large cell bodies (blue) with thicker extensions (pale green). Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body. Glial cells are nervous system cells that provide the neurons with structural support and protection-PI...
✯ Nerve cells. Coloured scanning electron micrograph (SEM) of nerve cells, showing cell bodies (pink) and extensions called axons and dendrites (purple). Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body.✯
Human embryonic stem cells differentiating into RPE precursors cells of the retina. Nuclei are in blue. Pink indicates the presence of Pax6, a protein found in retinal tissue. The retinal pigment epithelium is the tissue responsible for macular degeneration, the most common cause of blindness. | This photo was taken by David Buchholz in the lab of Dennis Clegg at the University of California, Santa Barbara.
Confocal micrograph showing the expression of different fluorescent proteins in the stem of a thale cress seedling (Arabidopsis thaliana). Arabidopsis was the first plant to have its entire genome sequenced and is an important model for studying plant biology. The middle of the image shows a region of high cell proliferation, which drives the growth and branching of the seedling.

"Leprosy bacteria use 'biological alchemy'-Infectious bacteria have for the first time been caught performing "biological alchemy" to transform parts of a host body into those more suited to their purposes...The study...showed leprosy-causing bacteria turning nerves into stem cells and muscle...Prof Chris Mason, a specialist in stem cell research at University College London, said: "The ability of bacteria to convert one mammalian cell type to another is 'alchemy' by nature on a grand scale..."
