Tissue Transglutaminase Staining Pattern of Reticular Cell Types in Reactive Lymph Node

Cell type	Surrounding primary follicle	Surrounding secondary follicle	Surrounding regressed follicle
FRC	TG−	TG++	TG−/+
SLC	TG++, plump	TG+, flattened	TG+, inconspicuous
CLA+ HEV	TG−/+, inconspicuous	TG++, prominent	TG−/+, variable
TG+ dendritic forms	Few	Few	Increased in PTGC follicles

Staining intensity of tissue TG was graded as intense (++), moderately intense (+), variably positive (−/+), and dim/negative (−).
