Are we really facing a STEM crisis? Or is this crisis as bogus as the missile gap that started the space race over 50 years ago? It's time to cut through the hyperbole and take a hard look.

The Stemness of Perinatal Stem Cells
2019Perinatal tissues provide a list of new sources for stem cell derivation, such as amniotic fluid, fetal membranes (amnion and chorion), umbilical cord, and placental tissue. The perinatal stem cells represent an intermediate cell type which has recently been described to combine qualities of both adult stem cell and ESCs and possess a broad multipotent

Abstract In PIE there were consonant stems ending with -r- (paradigms given in 283). Masc. and fem. nouns thus formed are attested in all varieties of IE. Neut. inflection is more fugitive. In lndic, the reflex of the nomenagentis suffix “-tor builds a kind of future participle (555); a few neut.

New technologies have had a major impact on the mapping of the brain stem. Gene expression and inducible genetic fate mapping have revealed the presence of a segmental organization, which includes two midbrain segments, the isthmus, and 11 rhombomeres. The cerebellum has been shown to be an outgrowth of the isthmus and the first rhombomere.

Differentiation, 2005
This essay is focused on a specific line of research toward regenerative therapies that is based on the use of embryonic stem cells but tries to avoid cloning techniques that are the heart of current ethical debates.

New England Journal of Medicine, 1978
Blood cells, like blossoms of a floribunda, arise together from a single branch. Clinicians have long assumed that granulocytes, megakaryocytes and erythroid cells have a common origin because all three cell lines may be involved to a varying degree in the many forms of myeloproliferative disease.

Stem Regularisation, Stem Synthesis and Stem Production in Tat
2019Tat tense-aspect-mood (TAM) categories, like in many Iranian languages, feature a binary stem distinction, whereby either stem represents the morphological nucleus of a given TAM category. The morphological distribution of the two stems in Tat resembles that in Persian.
