Frequencies of Immune Cells in the Human Small Bowel During Normal Gestation and in Necrotizing Enterocolitis.

Throughout gestation, we found an increase of all examined immune cell types in the normal small bowel, while the number of B cells came to a standstill at midway. Future studies should examine subtypes of T cells and also include histiocytes. A larger amount of small bowel specimens, covering the full gestational age, would be of great value.
