From: In vivo study of the immune response to bioengineered spider silk spheres

The phenotypes of the cells infiltrating the spheres 1 day after implantation. Mice were subcutaneously administered Matrigel loaded with PBS or MS1 or H2.1MS1 spheres, and 1 day after injection, the implants were excised and pooled among the groups; infiltrating immune cells were analyzed by flow cytometry. (a) CD4+ lymphocytes (CD45+CD3+CD4+), (b) CD8+ lymphocytes (CD45+CD3+CD8+), (c) Treg lymphocytes (CD45+CD3+CD25+FoxP3+), (d) B lymphocytes (CD45+CD3−CD19+), (e) macrophages (CD45+CD14+), and (f) NK cells (CD45+CD3−CD16/56+).
