An Extended Culture System that Supports Human Primordial Germ Cell-like Cell Survival and Initiation of DNA Methylation Erasure

In this study we describe a two dimensional extended culture system that promotes proliferation of specified hPGCLCs, without reversion to a pluripotent state. We demonstrate that hPGCLCs in extended culture undergo partial epigenetic reprogramming, mirroring events described in hPGCs in vivo, including a genome-wide reduction in DNA methylation and maintenance of depleted H3K9me2. This extended culture system provides a new approach for expanding the number of hPGCLCs for downstream technologies, including transplantation, molecular screening, or possibly the differentiation of hPGCLCs into gametes by in vitro gametogenesis.Graphical Abstract

Purpose of review This review provides a risk-stratified and evidence-based management for subsets of systemic sclerosis (SSc) patients in the first five years from disease onset. Recent findings Cardiopulmonary disease remains the primary cause of mortality in SSc patients. Morbidity and mortality in SSc-associated pulmonary arterial hypertension have improved with combination treatment, in either an upfront or sequential treatment pattern. Traditional therapies for interstitial lung disease (SSc-ILD) have targeted those with clinically significant and progressive ILD with immunosuppression. New data suggest a possib...

This study investigated the effects of human umbilical-cord mesenchymal stem cells (HUMSCs) injection on diabetic rat model. The results show that the level of MIAT is significantly decreased in the diabetic retina after the injection of HUMSCs. Moreover, HUMSCs can significantly decrease the expression of IL-1β and IL-6 mRNA; alleviate microvascular permeability, and upregulate Occludin expression. Studies have shown that MIAT knockdown could alleviate diabetes-induced inflammation responses and vascular leakage. Furthermore, our findings also showed that the expression of MIAT was positively correlated with the expr...

CONCLUSIONS: The HLCs attenuated liver fibrosis more efficiently when transplanted along with HUVECs and AMSCs, and this suggested that we could improve the efficiency of cell therapy by transplanting functional cells partially along with stromal cells. PMID: 32211118 [PubMed]

BACKGROUND Penetrating traumatic brain injury induces chronic inflammation that drives persistent tissue loss long after injury. Absence of endogenous reparative neurogenesis and effective neuroprotective therapies render injury-induced disability an unmet need. Cell replacement via neural stem cell transplantation could potentially rebuild the tissue and alleviate penetrating traumatic brain injury disability. The optimal transplant location remains to be determined. METHODS To test if subacute human neural stem cell (hNSC) transplant location influences engraftment, lesion expansion, and motor deficits, rats (n = 10...

Outcomes in high ‐risk acute monocytic leukemia‐M5 children with only conventional chemotherapy remain unsatisfactory, and hematopoietic stem cell transplant (HSCT) has proven to be beneficial especially in FMS‐like tyrosine kinase 3‐internal tandem duplication carriers, age ≤ 3 years old and hyperleuko cytic patients. The choice of HSCT should be made more carefully in a defined subgroup withMLL ‐R for its suboptimal performance. AbstractBackgroundThe prognosis of children with acute monocytic leukemia (AML ‐M5) remains unsatisfactory and the risk profile is still controversial. We aim to inv...

Thiotepa is a common alkylating agent known to precipitate cutaneous reactions consistent with toxic erythema of chemotherapy, including erythema and hyperpigmentation. Herein, we describe an atypical case of malignant intertrigo involving preferential erythema and desquamation not only of skin folds but also of occluded areas after thiotepa-based conditioning. The diagnosis was complicated by concurrent stomatitis and oral petechiae in the setting of autologous stem cell transplant 11 days prior for diffuse large B-cell lymphoma. Histopathological examination from two cutaneous sites demonstrated epidermal dysmaturation a...
