[Timing of the rudiments and manner of lymph node formation in the mesenteries of different segments of the human large intestine].
The first anlages of the mesenteric lymph nodes in the human transverse and sygmoid colons have been stated by means of common histological methods to appear on the 14th week of the intrauterine development. The lymph node anlages in the colon mesentery are appearing during the whole period of embryogenesis. The lymph nodes are formed as a result of condensation of mesenchymal cells near the external surface of the dilated lymph vessel wall or between two or several vessels.
