INTRODUCTION. The rhesus macaque shares many common structural and physiological features with the human female reproductive tract, including similarity of uterine gross anatomy, and generally analogous morphological changes within the endometrium during the proliferative and secretory phases of the natural day menstrual cycle.

In the present study we investigated the expression and regulation of HTRA3 mRNA and protein in the non-pregnant rhesus monkey ovary and endometrium, and at the maternal-fetal interface during early pregnancy.
We propose that similar to the findings in the rodent, HTRA3 may be associated with folliculogenesis and luteinisation in the primate by: The factors that produce vascular variability also control the cyclic changes in the parenchymatous tissues of the endometrium, in large part secondarily via the blood vessels.
The latter may therefore with justice be regarded as dynamic determinants of endometrial activity and as such merit a detailed consideration of their anatomy and physiology. Prior toobservations of both nonpregnant and pregnant uterine vascular changes consisted of descriptive morphology (Ramsey, ) and descriptive physiology.
The latter was limited by the primitive technologies then available. In his classic studies, Markee () described cyclic changes in endometrium transplanted into the eyes of by: 8. Rossman's term 'deciduomal' has been retained in the present study to distinguish the epithelial reaction of the endometrium to trauma in the rhesus monkey from the stromal, decidual cell reaction.
This observation has been fully confirmed and amplified in an elaborate study of the vascular pattern of the endometrium of the pregnant rhesus monkey by Ramsey (86). These observaï¿½ tions give point to the view expressed by Hasner (87) that we should think of the endometrial coiled arterioles not as a device to provide for menstruation.
Introduction. The development of the mammalian embryo depends critically upon the formation of a functional placenta. During the process of hemochorial placenta formation (as in rodents and primates), the fetally derived trophoblast is invading the decidua and breaching uterine vessels; as a result, maternal blood is in direct contact with the trophoblast .Cited by: In a previous study on the normal human endometrium involving the proliferative, secretory and post‐menopausal endometrial samples, it was also demonstrated that AM expression in the endometrium became apparent in the late proliferative phase and became abundant in the secretory phase, concomitant with angiogenesis of the endometrium (Laoag Cited by: pregnant human, bonnet and baboon endometrium (Demir et al., ; Rosario et al., ).
Along with these changes, a few granulocytic stromal cells are also observed in the luminal epithelium of pregnant bonnet and rhesus monkeys prior to implantation (Ghosh et al., ; Rosario et al., ).
It is conceivable that these changes occur to. Human blood is grouped into four types: A, B, AB, or O. Each letter refers to a type of antigen found on the surface of red blood cells.
For example, Type A blood has antigens known as A-antigens. Each blood type is also grouped by its Rhesus factor (Rh). Rhesus is another type of antigen on the surface of red blood cells.
Macaques are menstruating nonhuman primates that provide important animal models for studies of hormonal regulation in the uterus.
In women and macaques the decline of progesterone (P) at the end of the cycle triggers endometrial expression of a variety of matrix metalloproteinase (MMP) enzymes that participate in tissue breakdown and menstrual sloughing.

5α-Dihydroprogesterone is an active progestogen; it has about 82% of the affinity of progesterone for the rhesus monkey progesterone receptor and about 33% of the relative progestogenic potency of progesterone.

Unlike other smooth muscle organs, the uterine muscle was regarded to be normally functional for only a brief period, following a lengthy gestation.
However, recently it has been shown that uterine peristalsis constitutes one of the fundamental functions of the non-pregnant uterus.
