The outcome of a given division is unpredictable, but in homeostasis the probabilities of producing two progenitor and two differentiating daughters are the same, so that on average, equal numbers of progenitors and differentiating cells are produced across whole population of progenitors.

Positive clones were then differentiated using defined serum - free conditions outlined in Ng, et al [7], which overall gave rise to a CD45 + CD56 + CD117 − CD94 + population of cytotoxic NK cells [8] expressing the CD4 construct and other surface markers in a similar manner to peripheral blood NK cells.

Proteomics — the large - scale study of proteins, particularly their structure and function — combined with transcriptomics — the examination of the expression level of messenger ribonucleic acids (mRNAs) in a given cell population - played a significant role in the recent derivation of a combined protein and gene list that constitutes one of the largest descriptive data sets of its kind.

Nevertheless, the burst properties reported in this study strongly support the idea that the deeper layers of the SC act as an optimal controller: the systematic organization of peak firing rates and burst durations as function of saccade amplitude along the motor map, the synchronous change in firing rate of recruited cells in the population, and the shaping of the temporal burst profile of a given cell with the currently planned saccade, all contribute to the generation of straight eye - movement trajectories with optimal kinematics.

By looking for cell populations that would resemble the vertebrate chordamesoderm (a population of mesodermal midline cells that converge medially to give rise to the notochord; red in Fig. 1A), we identified segmental pairs of mesodermal cells on the non — bone morphogenetic protein (BMP) body side (5) that stood out by early and continuous expression of colA1, encoding collagen type A (Fig. 2, A to D).

This models depicts the ES cell as a highly plastic but nevertheless discrete and stable cellular entity, one that in turn gives rise through a massive switch in gene expression to discrete progenitor populations with more limited developmental potential.
