In addition, both cell populations expressed similar level of CD34 and CD144 at the RNA level (Figure 6b).
No significant differences were detected for NESTIN, NGF and PrP C mRNA levels between treated and untreated bMSC; however, both cell populations expressed higher (P < 0.05) levels of NESTIN at 24 h of culture.
Also, both human cell populations express TLR5 and are activated by flagellin [64], [65], [66], [67], [22].
In this work, we further characterize primary cultures of RGCs and HCs obtained from embryonic retinas at early stages in development by different procedures of purification; strikingly, both retinal cell populations express the nonvisual photopigment Opn4 (Opn4m and/or Opn4x) as well as components of the clock machinery needed to measure time to temporally adjust retinal physiology.
Here we show that both murine and human progenitor cell populations express this receptor subtype on transcriptional and protein levels and respond to its agonists by reduced growth factor-induced cell cycle progression that leads to decreased myeloid, erythroid and lymphoid colony formation.
Mature and very primitive hematopoietic cell populations express somewhat different cell surface antigens.
It was next determined whether a percentage of epithelial cells present in immortalized, premalignant cell populations express estrogen receptor-α (ER-α) or progesterone receptor (PR).
Despite this, the primitive embryonic epithelial and mesenchymal cell populations express a number of genes that have been shown or suggested to regulate postnatal progenitor mammary cell functions.
This raises the question of whether the low numbers of these cell populations express sufficient levels of mRNA transcripts for detection.
Both progenitor cell populations expressed IL7Rα upon 48 hours of cytokine stimulation, while no IL7Rα expression could be detected at hour 0 (Fig. S3).
