FIG. 5.

Comparison of results from lymph node samples obtained by either excisional biopsy or FNA. (A) Representative dot plots demonstrating scatter properties and mononuclear staining for samples obtained by excisional biopsy and FNA of the same lymph node are shown. SSC, side scatter; FSC, forward scatter. (B) Cumulative flow cytometry data on the distribution of CD3, CD4, and CD8 T cells in FNA or excisional biopsy (EB) samples from three subjects. (C) Homeostatic chemokine levels as measured by qPCR in lymph node samples obtained by FNA or excisional biopsy from three subjects.
