Kempermann believes there are: "The network requires very few cells to be added and still be functionally relevant," he says.
For the alginate group, there was little microbead degradation, with very few cells released at 21 d.
Some of the responses are very mild in that you get very little protein absorbed, you get very few cells recruited to the site.
The tissue sections showed that TUNEL-positive cells were concentrated in the stump epidermis, with very few cells observed in the mesenchyme (Fig. 3c; Fig. S3b).
There are very few cells in CSF, so it's highly unlikely that an implant located there would provoke an immune response.
Many T cells were identified within the tissue; however, the classical marker of activation, CD25 was expressed on very few cells.
In contrast, when cells with wild-type KRAS alleles were subjected to a low-glucose environment, very few cells survived.
Conversely, very few cells co-expressed the mature oligodendrocyte marker MBP (Figure 4H; see also below).
Very few cells expressing CD4, CD8 or CD3 were generated in this culture (data not shown).
Very few cells expressed Ki67 at 6 weeks, indicating that there was little proliferation.
However, it is difficult to exclude the possibility a very few cells become progenitor cells.
