投稿须知/期刊简介:
Stem Cell Reports is an open access forum communicating basic discoveries in stem cell research, in addition to translational and clinical studies. Stem Cell Reports focuses on shorter, single-point manuscripts that report original research with conceptual or practical advances that are of broad interest to stem cell biologists and clinicians. Given the rapidly increasing impact of stem cell research to regenerative medicine and tissue engineering, Stem Cell Reports encourages the submission of manuscripts whose scope bridges these fields of research. The journal also encourages the submission of reports of robust new methodologies with biological significance and/or the potential to advance the application of basic research from the laboratory to the clinic. Stem Cell Reports promotes transparency in stem cell research and related fields of research through the publication of confirmatory findings, negative results, and adverse events. Stem Cell Reports covers: Embryonic stem cells Adult stem cells Reprogramming to pluripotency and lineage conversion Directed differentiation Germ cells Genetic and epigenetic mechanisms Stem cells in development Stem cell niche Cancer stem cells Disease modeling and drug screening Stem cell therapy Clinical studies in regenerative medicine Tissue engineering and biomaterials Imaging and diagnostics Stem cell products, manufacturing, and quality control Ethical, legal, and social issues
期刊描述简介:
Stem Cell Reports is the official journal of the ISSCR and is published by Cell Press. The International Society for Stem Cell Research (ISSCR) is a non-profit, scientific membership organization providing a platform for professional and public education and the promotion of rigorous scientific and ethical standards in stem cell research and regenerative medicine. ISSCR members receive a discounted publication charge when publishing in Stem Cell Reports in addition to many other member benefits.

Deep-supercooling preservation of stem cell spheroids for chondral defect repairment.
Versatile mesenchymal stem cells (MSCs) play an important role in tissue engineering and regenerative medicine. MSCs in 3D spheroid have shown higher secretion and differentiation functions than suspended counterparts, and, thus, in vitro cryopreservation of MSC spheroids is an indispensable technology to bridge the spatiotemporal gaps between spheroid generation and application. Traditional cryopreservation methods are inapplicable for spheroid due to severe thermal stress, toxic cryoprotectants, and ice formation. Here, we constructed and preserved human MSC (hMSC) spheroids via deep supercooling (DSC). Spheroids were DSC preserved at -12°C without ice formation for 7 days, with higher cell viability, energy level, and chondrogenic differentiation capacity than suspended hMSCs. hMSCs embedded in spheroids have close cell-cell interactions via N-cadherin to activate the AKT-cytochrome c-caspase anti-apoptotic cascade during DSC preservation. Finally, preserved hMSC spheroids were capable of chondrogenic differentiation and can be co-delivered with collagen to treat rat cartilage defects in vivo.

Development of adeno-associated viral vectors targeting cardiac fibroblasts for efficient in vivo cardiac reprogramming.
Overexpression of cardiac reprogramming factors, including GATA4, HAND2, TBX5, and MEF2C (GHT/M), can directly reprogram cardiac fibroblasts (CFs) into induced cardiomyocytes (iCMs). Adeno-associated virus (AAV) vectors are widely used clinically, and vectors targeting cardiomyocytes (CMs) have been extensively studied. However, safe and efficient AAV vectors targeting CFs for in vivo cardiac reprogramming remain elusive. Therefore, we screened multiple AAV capsids and promoters to develop efficient and safe CF-targeting AAV vectors for in vivo cardiac reprogramming. AAV-DJ capsids containing periostin promoter (AAV-DJ-Postn) strongly and specifically expressed transgenes in resident CFs in mice after myocardial infarction (MI). Lineage tracing revealed that AAV-DJ-Postn vectors expressing GHT/M reprogrammed CFs into iCMs, which was further increased 2-fold using activated MEF2C via the fusion of the powerful MYOD transactivation domain (M-TAD) with GHT (AAV-DJ-Postn-GHT/M-TAD). AAV-DJ-Postn-GHT/M-TAD injection improved cardiac function and reduced fibrosis after MI. Overall, we developed new AAV vectors that target CFs for cardiac reprogramming.

Tropomyosin 1 deficiency facilitates cell state transitions and enhances hemogenic endothelial cell specification during hematopoiesis.
Tropomyosins coat actin filaments to impact actin-related signaling and cell morphogenesis. Genome-wide association studies have linked Tropomyosin 1 (TPM1) with human blood trait variation. TPM1 has been shown to regulate blood cell formation in vitro, but it remains unclear how or when TPM1 affects hematopoiesis. Using gene-edited induced pluripotent stem cell (iPSC) model systems, we found that TPM1 knockout augmented developmental cell state transitions and key signaling pathways, including tumor necrosis factor alpha (TNF-α) signaling, to promote hemogenic endothelial (HE) cell specification and hematopoietic progenitor cell (HPC) production. Single-cell analyses revealed decreased TPM1 expression during human HE specification, suggesting that TPM1 regulated in vivo hematopoiesis via similar mechanisms. Analyses of a TPM1 gene trap mouse model showed that TPM1 deficiency enhanced HE formation during embryogenesis, without increasing the number of hematopoietic stem cells. These findings illuminate novel effects of TPM1 on developmental hematopoiesis.

The impact of consanguinity on the design of iPSC banks.
The effect of consanguinity on identifying universal induced pluripotent stem cell (iPSC) donors, i.e., homozygous for the major human leukocyte antigen (HLA) loci, is unknown. The discovery sample size was calculated in a consanguineous population using a method (1qF) based on the inbreeding coefficient. The result was orders of magnitude smaller compared to the standard method.

Self-assembling 3D vessel-on-chip model with hiPSC-derived astrocytes.
Functionality of the blood-brain barrier (BBB) relies on the interaction between endothelial cells (ECs), pericytes, and astrocytes to regulate molecule transport within the central nervous system. Most experimental models for the BBB rely on freshly isolated primary brain cells. Here, we explored human induced pluripotent stem cells (hiPSCs) as a cellular source for astrocytes in a 3D vessel-on-chip (VoC) model. Self-organized microvascular networks were formed by combining hiPSC-derived ECs, human brain vascular pericytes, and hiPSC-derived astrocytes within a fibrin hydrogel. The hiPSC-ECs and pericytes showed close interactions, but, somewhat unexpectedly, addition of astrocytes disrupted microvascular network formation. However, continuous fluid perfusion or activation of cyclic AMP (cAMP) signaling rescued the vascular organization and decreased vascular permeability. Nevertheless, astrocytes did not affect the expression of proteins related to junction formation, transport, or extracellular matrix, indicating that, despite other claims, hiPSC-derived ECs do not entirely acquire a BBB-like identity in the 3D VoC model.
