stem

the part of the shoot of vascular plants from which are produced leaves at regular intervals (NODES) and reproductive structures. Stems are usually circular in cross section but some are square (for example, members of the family Labiatae, such as mint and lavender) while others are ribbed. The internal structure of stems can be herbaceous (non-woody) or show SECONDARY THICKENING. See Fig. 289 .

The forms adopted by stems are highly varied, ranging from the oak tree to climbing plants such as Clematis and the pea. Stems are sometimes used as underground storage organs as in RHIZOMES, CORMS, BULBS (underground shoots with food stored in fleshy leaves) and stem TUBERS, e.g. potato, while others, such as the strawberry RUNNER and suckers of mint, are adapted for VEGETATIVE PROPAGATION.

Patient discussion about stem

Q. my mother have stem replacement for a coronary artery oclusion is already 2 years she physically deteriorating since surgery why???? please help she does not have energy

A. I agree with Dagmar. It can be most likely caused by another occlusion or re-occlusion inside the heart blood vessels. Since that is a life-threatening case, I strongly suggest you to bring your mother into a hospital (for complete check up), or just call your cardiologist to have first treatment.

Meanwhile, that will be better if you have emergency oxygen (just in case you'll need it) with you.

Stem cells are still a relatively new discovery, as the first mouse embryonic stem cells were derived from embryos in 1981, but it was not until 1995 that the first successful culturing of embryonic stem cells from non-human primates occurred and not until November 1998 that a technique was developed to isolate and grow embryonic stem cells from human blastocysts.
