Consumer-goods rival Reckitt Benckiser, maker of Harpic surface cleaner and air freshener Air Wick, reported a 20% rise in sales for the second quarter last month.
Pruszak et al. (2009) demonstrated the utility of CD24, CD15 and CD29 as a surface maker code for isolating distinct cell populations, including NSC and a mixed population of neuroblasts and neurons from neural induction cultures of hESC [30].
These findings did not necessarily imply that the very same cell surface maker that immunologists use to type T-cell subsets would be recognized by HIV.
In addition, cancer stem cells typically represent a small number of the total tumor cells which can be enriched on the basis of cell surface maker expression.
To analyze the surface maker expressed on pluripotent stem cells, they were stained with no-conjugated primary SSEA-4, TRA-1-60, and TRA-1-81 antibody, respectively, and further stained with species-specific secondary antibodies conjugated to Alexa Fluor® 448 (Invitrogen).
Three characteristic surface makers expressed by ECs were studied using immuno-florescent microscopy.
The extent of Wnt activation was positively correlated with expression of well-studied cell surface makers for CSCs [63].
