Stem Cells

Human embryonic stem cells

Mesenchymal stem cell. Coloured scanning electron micrograph (SEM) of a human mesenchymal stem cell (MSC). MSCs are multipotent stromal (connective tissue) cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), and adipocytes (fat cells). The youngest, most primitive MSCs can be obtained from the umbilical cord tissue. Magnification: x4500 when printed 10 centimetres wide. Credit: STEVE GSCHMEISSNER/SCIENCE PHOTO LIBR...

Bone marrow stem cell. This beauty can turn into any type of blood cell!

Plant cells

Neurons (in blue to yellow) growing on top of astrocytes (in red, helper cells within the nervous system) in a human stem cell embryoid body (a cluster of differentiating human embryonic stem cells).

neural stem cells

This neuronal stem cell culture shows a rainbow of differentiation, with fluorescent tags that separate stem cells (orange/yellow) from their neuronal "offspring" (blue/green/purple).

A human blood sample showing red cells, white cells, platelets (coloured yellow/green) and fibrin (light brown). The image was captured by field emission scanning electron microscope.

Researchers at the Royal College of Surgeons in Ireland (RCSI) have developed a new method of repairing bone using synthetic bone graft substitute material, which combined with gene therapy, can mimic real bone tissue and has potential to regenerate bone in patients who have lost large areas of bone from either disease or trauma.

Starry Night, so named because it reminded astronomers of the Van Gogh painting. It is a halo of light around a star in the Milky Way

Intricate Intelligent Design: Salt water centric diatom frustule (skeleton). Diatoms are microscopic, unicellular algae that produce intricate silica (glass) cell walls that overlap like the top and bottom of a box. When diatoms die, their soft, internal parts deteriorate, leaving their hard, porous, glass skeletons behind. Diatoms are found in aquatic environments.
