The placenta of the guinea-pig has assumed exceptional importance
among the discoidal hemochorial placentae since the end of the
sixties. Up to that date, numerous studies had been published on
the functional analysis of the human placenta. One shortcom- ing
common to all these studies, however, was the fact, that the human
placenta was not absolutely suitable for morphological research,
owing to fIxation difficulties, and for experimental investigations
virtually unsuitable. Since other hemochorial villous placentae,
like that of the anthropoid apes (primates) were practically
unobtainable, a possible alternative was sought among the I;tcunal
placentae. The numerous studies on the guinea-pig placenta
undertaken at the turn of the century favoured the choice of this
organ as it also belonged to the discoidal hemochorial type, like
that of man. The fact that its structure was not villous but
lacunal and therefore showed a different cir- culation seemed even
advantageous in this case. The lacunal system facilitates differen-
tiation in morphologically distinct areas, which allow independent
functional analysis. The morphological and histochemical studies
made during the past decade by Enders (1965), Vollrath (1965),
Miiller and Fischer (1968), Kaufmann (1969a), Davidoff and
Schiebler (1970a, b), King and Enders (1970b, 1971), Davidoff and
Gospodinoff (1971), Davidoff (1973), Kaufmann (1974) have led to
the discovery of a large amount of new information on this organ,
thus rendering it one of the most precisely examined placentae so
far.
