Similarly, observations of the nearby SN PTF 11kx, discovered January 16, 2011 (UT) by the Palomar Transient Factory (PTF), lead to the conclusion that this explosion arises from single-degenerate progenitor, with a red giant companion, thus suggesting there is no single progenitor path to SN Ia.
It has been proposed that Leptospira had a common progenitor with a genome resembling to that of L. biflexa.
Strains 15310, 15311 and NEA12 show near-identity in all individual gene-based trees, indicating a low level of intra-group diversity, and reflecting a probable recent origin from an E. festucae-like progenitor with a MTB idiomorph.
Where else, after all, could you find a city that celebrates mythological child-murderess Medea (of Jason and the Argonauts fame -- Medea was allegedly from the kingdom of Colchis, Batumi's ancient progenitor) with an enormous, million-dollar gold statue located in the city's Europe Square?
As to the second question, the reappearance of massive W tracts in Drosophila can be quoted in favor of independent (convergent) evolution, while if conservation would be the answer, an early progenitor with only a binary code could be suspected.
We describe multiple progenitor subgroups, showing unexpected transcriptional priming toward seven differentiation fates but no progenitors with a mixed state.
In conclusion, our study of the epigenetic plasticity of adult RPE revealed the similarity of these cells to progenitors with a high ability for EMT.
The paper is titled "Accumulation of multipotent progenitors with a basal differentiation bias during aging of human mammary epithelia". Co-authors are James Garbe, Francois Pepin, Fanny Pelissier, Klara Sputova, Agla Fridriksdottir, Diana Guo, Rene Villadsen, Morag Park, Ole Petersen, Alexander Borowsky and Martha Stampfer.
Loss of function of the two PCP core components Celsr2 and Celsr3 shows that they control the differentiation of endocrine cells from polarized progenitors, with a prevalent effect on insulin-producing beta cells.
During pancreatic development in rodents, beta cells are derived from Pdx1-positive progenitors with a high proliferative potential [6], [7].
O2A progenitors with a more reduced state have a greater likelihood of self-renewal compared to cells with a more oxidized state.
