Stem cells (SCs) play an important role in autologous and even allogenic applications. Menstrual blood discharge has been identified as a valuable source of SCs which are referred to as menstrual blood-derived stem cells (MenSCs). Compared to SCs from bone marrow and adipose tissues, MenSCs come from body discharge and obtaining them is non-invasive to the body, they are easy to collect, and there are no ethical concerns. There is, hence, a growing interest in the functions of MenSCs and their potential applications in regenerative medicine.
This review presents recent progress in research into MenSCs and their potential application. Clinical indications of using MenSCs for various regenerative medicine applications are emphasized, and future research is recommended to accelerate clinical applications of MenSCs. The endometrium undergoes more than 400 cycles of regeneration, differentiation, and shedding over the whole reproductive period of a woman. Human endometrial stem cells play an important role in this cyclic regeneration and repair. Endometrial stem cells (EndoSCs), including epithelial, stromal, and endothelial cells, may contribute to the periodic endometrial regeneration [ ], mainly reside in the perivascular region of both the basalis and functionalis of the endometrium [ ].
When exfoliated in the menstrual blood, these EndoSCs are hence referred to as the menstrual blood-derived stem cells (MenSCs) [ ]. The advantages of MenSCs include non-invasiveness of extraction, high proliferation ability, and short doubling time, and maintenance of chromosome karyotyping after up to 68 generations, which qualifies MenSCs as an ideal source of regenerative cells desperately needed for transplantation, neurological disorders, and cancer therapy, etc.
Bayesian 3D Modeling from Images using Multiple Depth Maps Pau Gargallo and Peter Sturm INRIA Rhone-Alpes,‹ GRAVIR-CNRS, Montbonnot, France Abstract This paper addresses the problem of reconstructing the ge-ometry and color of a Lambertian scene, given some fully calibrated images acquired with wide baselines.
The endometrium, which consists of luminal epithelium, glandular epithelium, and an extensively vascularized stroma, structurally and functionally falls into two compartments, viz, functionalis and basalis [ ]. Endometrial glands are lined with pseudo-stratified columnar epithelium extending from the luminal epithelium to the endometrial/myometrial junction. The functionalis consists of the upper two thirds of the glands surrounded by loose vascularized stroma. Being a germinal supplier for new functionalis replacement in each cycle, the basalis is composed of the lower one thirds of glands, stroma, and large vessels [ ].
Gargett et al. Considered that human endometrial stem cells include epithelial progenitor cells, endometrial mesenchymal stem cells (eMSCs), and endothelial progenitor cells [ ], while Evans et al.
Characterized endometrium-specific stem cells into epithelial progenitor cells, side population (SP) cells, and eMSCs [ ]. Latihan soal uas matematika kelas 2 sd semester 1 chemistry 2017. Endometrial epithelial progenitor cells Within the first 48 h of menses, with stumps of the gland remaining in the basalis, a rapid repair and re-epithelization of the endometrium lining occurs to cover the exposed basal surface. Epithelial progenitor cell populations locate within the residual glands of the basalis [ ]. Evidence was provided by the presence of colony-forming units (CFUs) in suspension cells from hysterectomy specimens [ ]. These large single cell-derived epithelial CFUs have high proliferative potential and can differentiate into large glandular-like structures in 3D culture [ ]. Although pluripotent stem cells can be isolated from endometrial biopsies or menstrual blood, epithelial progenitor cells cannot be obtained from menstrual blood, either because they are not present in the menstrual blood or because they are simply eclipsed by the huge amount of stromal fibroblast populations [ ]. Previous study has implied that the niche of epithelial progenitor cells is more likely to be in the basal layer than in the functional layer [, ].
