When the extremity is constricted there can be swelling of the distal tissues, developmental abnormality with physical deformity or even complete amputation. The type of abnormality depends on two events:. Under rare circumstances an amniotic band can also affect development of other parts of the body. For example, a band that passes over the face has been associated with cleft lip and even clef palate.
In cases where the amniotic band encircles the umbilical cord of the fetus, obstruction of blood supply can lead to fetal death. These last two complications are relatively rare. It is typically very difficult to detect amniotic band syndrome before birth, but the condition can sometimes be detected via ultrasound.
Many times amniotic band syndrome is diagnosed after delivery during a physical examination of the newborn. Our team partners with patients and their families to deliver personalized care for a wide range of complex prenatal conditions.
The treatment options for amniotic band syndrome include in utero fetal surgery and postnatal repair of the resulting abnormalities. Fetal surgery : The goal Amniotic Sciences fetal surgery is to release the constriction caused by the amniotic band before it can cause further damage.
This is done by operative fetoscopy, which allows the direct visualization of the amniotic band and its release using various surgical techniques. The success of fetal surgery depends on the degree of damage that has been caused by the amniotic band.

And then, sections were incubated with corresponding biotinylated secondary antibodies Vector Laboratories, Burlingame, Ca, USA; followed by avidin—biotin—peroxidaseand the immunoreactivity was visualized with 0.
The images of tube-like structure were acquired under a light microscope, and the length of tube was measured using WimTube Quantitative Tube Formation Image Analysis Software. The mean and standard error of the mean SEM were calculated for experimental variables. Results showed that many mature and healthy follicles existed in both ovaries of mouse in the sham group Fig.
In contrast, many atretic follicles were observed in ovaries from chemo-ablated group Fig. However, no mature follicles existed in the contralateral ovary right ovary, un-injection side of the same mouse Fig.
Pictures b, d, f, h, j, l, n, p, r and t were magnifications of the square in photos a, c, e, g, i, k, m, o, q and s, respectively. These results indicated that hAECs-secreting cytokines played an important role in hAECs-mediated the recovery of ovarian function after chemotherapy. Histological results showed that many healthy follicles were observed in both hAECs and hAEC-CM injection groups, yet no mature follicles were found in chemotherapy-treated ovaries Fig.
However, slight effect was observed in the primordial follicles and primary follicles in the chemo-injured ovaries. In addition, hAEC-CM treatment Amniotic Sciences be effective to promote the development and survival of follicle in injured ovaries. Follicular development and counting in the injured ovaries. The analytical standard used in this research was set up as follows: 1 The intensity of chemoluminescence intensity should be over in the hAEC-CM group.
According to Gene Ontology Enrichment Analysis GOEASTwe classified these cytokines into four groups, which are important in the hAECs-mediated the recovery of ovarian function, including regulation of apoptosis 37 proteinsAmniotic Sciences response 34 proteinsangiogenesis 24 proteins and regulation of cell cycle 16 proteins Fig. After analyzing the interactions and functional network identified by the Ingenuity Pathway Analysis IPA using the highest confidence, 0. The relative expression of these cytokines was defined as the ratio of certain cytokine to BMP15, as showed in Fig.
Cytokine array was performed to detect specific cytokines in conditioned medium of hAECs. To investigate the effect of hAEC-CM on chemotherapy-induced granulosa cells damage, Amniotic Sciences, primary human granulosa-lutein hGL cells were collected from the follicular fluid to perform experiments in vitro.
Results displayed that these cells highly expressed granulose cell-specific markers FSHR and Foxl2 and mesenchymal marker N-cadherin as well as the low of epithelial marker E-cadherin Additional file 1 : Figure S1B, a-h. However, hAECs could partially reverse chemotherapy drugs-induced cell damage in co-culture systerm Fig.
CCK-8 cell viability assay also displayed the consistent results with morphology Fig. Taken together, primary hGL cells were sensitive to chemotherapy drug. Amount of protein loaded was normalized against actin.
According to cytokine array results, we further investigate whether hAECs restore ovarian function via activating Smad pathway in granulosa cells. These results indicated that hAECs-secreting cytokines could activate Smad pathway of human luteinized granulosa cells in vitro. It is well established that chemotherapy irreversibly induced a loss of follicles and decreased microvascularization of the corpora lutea and follicles in a dose-dependent manner [ 21 ].
The microvessel density of CDpositive cells in the Cy-treated group was significantly lower than that in Sham group. Photographs e, f, g and h were magnifications of the square in photos a, b, c and d, respectively. B Quantification showed the density of CDpositive microvessel in injured ovary of different groups.
Fertility preservation is a critical consideration for young female cancer patients after receiving chemotherapy.
Transplantation of stem cells, including human amniotic epithelial cells [ 12 ], human endometrial mesenchymal stem cells [ 23 ], skin-derived mesenchymal stem cells [ 24 ] and human amniotic fluid stem cells [ 25 ], holds great promise as a potential preventive strategy to reduce ovarian injury in female patients accepting chemotherapy. However, the underlying molecular mechanism is still unclear.
In a previous study, we found that direct trans-differentiation of hAECs into granulosa cells in the injured ovary was a rare event and might play only a minor role [ 13 ], indicating that hAEC-secreting cytokines might play more important role in the hAEC-mediated ovarian function recovery. This discrepancy might be that secretary function and viability of hAECs in the condition of normal culture in vitro is different from chemotherapy-induced pathological environment in vivo.
A growing body of evidence suggests that stem cells promote the recovery of injured tissue via secreting factors [ 262728 ]. In the current study, we have confirmed that cytokines secreted by hAECs reduce the expression of cleaved caspase3 protein, and promote angiogenesis against CTX-induced damage in vivo and in vitro. In addition, it is vital to regulate steroidogenesis in granulosa cells [ 3536 ] and impact the expression of follicular development-related genes, such as connexin43 [ 37 ], connective tissue growth factor [ 34 ], Cyclooxygenase-2 and prostaglandin E2 [ 38 ].
Furthermore, we found that hAEC-secreting factors exerted restorative function on chemotherapy-induced vascular injury in vivo and protective ability against CTX-induced apoptosis in human granulosa cells in vitro.
The mechanism of hAECs-mediated ovarian function recovery after chemotherapy is complicated. Exosomes are small vesicles that originate from endocytic multivesicular compartments and are secreted by a variety of cell types, which mediate cell-to-cell or cell-to-environment communication [ 39 ]. It is known that multiple microRNAs are involved in the formation of primordial follicles, follicular recruitment and selection, follicular atresia, oocyte-cumulus cell interaction, granulosal cell function and luteinization [ 40 ].
Study has reported that exosomal microRNA10a derived from amniotic fluid stem cells preserves ovarian follicles after chemotherapy [ 41 ]. Our further study has confirmed the existence of hAEC-derived exosomes data not shown.
Thus, these specific microRNAs in hAECs-exosomes and their function in the process of ovarian function recovery will be elucidated in the future study. The present study demonstrated the presence of paracrine pathway accounting for hAEC-mediating recovery of ovarian function through inhibiting apoptosis and stimulating angiogenesis in the chemotherapy-injured ovaries.
This paradigm may offer novel insights into potential mechanism underlying the protective function of hAECs against chemotherapy-induced ovarian damage. Schematic diagram illustrated the two possible mechanisms responsible for the restoration effects of hAECs-based therapy. Moreover, paracrine pathway plays a vital role in hAECs-based recovery of ovarian function depending on the fact that hAEC-CM produced a comparable and potentially better effect.
These novel insights offer a clue to the potential mechanism underlying hAEC-mediating ovarian function recovery, which may be able to preserve the fertility in female cancer patients.

The amniotic fluid (AF) is an invaluable source of organ-specific progenitor cells and stem cells that are easily obtainable, expandable over multiple passages, and can be used in various regenerative medicine applications. From: Kidney Transplantation, Bioengineering and Regeneration, Stem cells derived from amniotic fluid and membranes possess embryonic stem cell-like differentiation capability and, similar to mesenchymal stem cells, are also able to modulate the local immune response. Their reduced immunogenicity and immunomodulatory properties allow their use in allo and xeno-transplantation settings. In development, the amnion arises by a folding of a mass of extra-embryonic tissue called the somatopleure. Lined with ectoderm and covered with mesoderm (both are germ layers), the amnion contains a thin, transparent fluid in which the embryo is suspended, thus providing a cushion against mechanical injury.
