Currently, examination of the cellular structure of plant organs and the gene expression therein largely relies on the production of tissue sections. Here, the authors present a staining technique that can be used to image entire plant organs using confocal laser scanning microscopy. This technique produces high-resolution images that allow three-dimensional reconstruction of the cellular organization of plant organs.

Stem cells from fat tissue transplanted into heart

Doctors have implanted adult stem cells extracted from a man's fat tissue through liposuction into his heart, in an experimental treatment for angina and heart disease, a Spanish hospital said on Tuesday.

Stem cells are master cells in the body that can transform in any type of cell or tissue. Scientists believe they could one day be used to treat a range of diseases.
In just five hours approximately the cells were extracted, purified, selected and implanted with the aim of regenerating new blood vessels which may allow them to flow blood properly to the heart of the patient
