Abstract: The development of lymphoid organs depends on the correct
expression of several molecules within a defined timeframe during ontogeny.
Although this is an extremely complex process, with each secondary lymphoid
tissue requiring subtly different signals, a common framework for lymphoid
development is beginning to emerge. So, we selected three species of the most
common Egyptian rats,Arvicanthis niloticus, Microtus agrestis and Acomys
cahirinus to determine whether or not there are
interspecific differences in their lymph nodes. The possibility of
interspecific differences is important because the selected species represent
three significantly different size categories (small, represented byM. agrestis,
moderate represented by A. cahirinus, and large represented by A.
niloticus) with presumably different diets and different physiologic
strategies. Also, the random
variations of the lymph node number within species of A. niloticus, M.
agrestis and A. cahirinus were noted. These
individual variations are remarkable in the posterior cervical, brachial,
internal jugular and axillary lymph groups.
