1. Pieces of small intestine taken from rabbit, rat, mouse, guinea-pig, hamster and pig have been used to determine microvillus length in enterocytes located at different points along the crypt-villus axis. Thymidine labelling has also been used to convert measurements of enterocyte position into age of enterocyte.
2.
2. Microvillus lengths showed lower and upper plateaux (
a and
a +
c respectively) with fairly rapid transition from one to the other defined by an exponential coefficient
b. The mid-point of elongation (
m) usually occurred within 60 μm of the crypt-villus junction.
3.
3. Correlations were found to exist between
a and
m and between
a,
m and the depth of the intestinal crypt. Values of
b and
bc/4. the maximal rate of microvillus elongation, were also found to be correlated with the size of the crypt.
4.
4. None of these parameters were related in any way to the villus height or enterocyte turnover time.
5.
5. The possibility that some factor associated with the physical size of the crypt might be exerting positional and temporal control over the subsequent structural differentiation of enterocytes is discussed. |
