Abstract
Direct reprogramming of somatic cells into functional cells still faces major limitations in terms of efficiency and achieving functional maturity of the reprogramed cells. While different approaches have been developed commonly based on exploiting biochemical signals, introducing appropriate mechanical cues that stimulate the reprogramming process is rarely reported. In this study, collagen-coated polyacrylamide (PAM) hydrogels with stiffness close to that of collagenous bone (40 kPa) were adopted to augment the direct reprogramming process of mouse fibroblasts to osteoblastic-like cells. The results suggested that culturing cells on a hydrogel substrate enhanced the overexpression of osteogenic transcription factors using nonviral vectors and improved the yield of osteoblast-like cells. Particularly, a synergistic effect on achieving osteogenic functionality has been observed for the mechanical cues and overexpression of transcriptional factors, leading to enhanced osteogenic transformation and production of bone mineral matrix. Animal experiments suggested that reprogramed cells generated on matrix hydrogels accelerated bone regeneration and stimulated ectopic osteogenesis. Mechanism analysis suggested the critical involvement of actomyosin contraction and mechanical signal-mediated pathways like the RhoA-ROCK pathway, leading to a synergistic effect on the key transcriptional processes, including chromatin remodeling, nuclear translocation, and epigenetic transition. This study provides insights into the mechanical cue-enhanced direct reprogramming and cell therapy.

Abstract
Somatic cell reprogramming was achieved by lentivirus mediated overexpression of four transcription factors called OSKM: OCT3/4, SOX2, KLF4, and c-MYC but it was not very efficient. Here, we reported that the transcription factor, LMCD1 (LIM and cysteine rich domains 1) together with OSKM can induce reprogramming of human dermal fibroblasts into induced pluripotent stem cells (iPSCs) more efficiently than OSKM alone. At the same time, the number of iPSCs clones were reduced when we knocked down LMCD1. Further study showed that LMCD1 can enhance the cell proliferation, the glycolytic capability, the epithelial-mesenchymal transition (EMT), and reduce the epigenetic barrier by upregulating epigenetic factors (EZH2, WDR5, BMI1, and KDM2B) in the early stage of reprogramming, making the cells more accessible to gain pluripotency. Additional research suggested that LMCD1 can not only inhibit the developmental gene GATA6, but also promote multiple signaling pathways, such as AKT and glycolysis, which are closely related to reprogramming efficiency. Therefore, we identified the novel function of the transcription factor LMCD1, which reduces the barriers of the reprogramming from somatic to pluripotent cells in several ways in the early stage of reprogramming.

Abstract
Induced pluripotent stem cells (iPSCs) hold promise in revolutionizing medicine; however, their application potential is limited because of low reprogramming efficiency. Mesenchymal-to-epithelial transition (MET) has been proved to involve reprogramming of somatic cells into iPSCs, making it a promising target for enhancing generation of iPSCs. Here, we nanoengineered N-cadherin-blocking peptide ADH-1 with gold nanoparticles, generating a multivalent N-cadherin antagonist (ADH-AuNPs), for improving reprogramming efficiency through driving cell MET. ADH-AuNPs exhibited good biocompatibility and showed higher N-cadherin inhibitory activity than ADH-1 due to multivalency, thereby enhancing cell-state reprogramming toward epithelial lineages. Particularly, ADH-AuNPs improved reprogramming efficiency by more than 7-fold after introduction of four Yamanaka factors. Importantly, ADH-AuNPs generated iPSCs displayed high stemness and pluripotency in vitro and in vivo. Therefore, we provide a cooperative strategy for promoting the iPSC generation efficacy.

Abstract
Somatic cell nuclear transfer (SCNT) is an important technique for biological science research. Cytoplasm injection cloning technology (CICT) was developed to improve the reprogramming efficiency as well as to overcome the limitations of SCNT. CICT uses an additional cytoplasm fused with an enucleated oocyte to restore the cytoplasmic volume of the cloned embryo, and this method could improve the reprogramming efficiency of the cloned embryo. In this study, we show that CICT can be adapted to mouse species to overcome the inefficiency of the SCNT method. In this study, results indicate that the two-cell embryo and blastocyst rates of cloned embryos with the use of the CICT method were significantly higher (p < 0.05) than that of the SCNT method (96.6% ± 1.1% vs. 86.7% ± 6.0%, 29.5% ± 2.6% vs. 22.1% ± 3.0%, respectively). Furthermore, the apoptotic cell number per blastocyst was significantly lower in the CICT group than that in the SCNT group (1.7 ± 0.2 vs. 2.9 ± 0.3, p < 0.05). Moreover, the acH3K9/K14 expression level in the CICT group was greater than that of the SCNT group (p < 0.05), and the relative acH3K56 level in the CICT group was significantly (p < 0.05) higher than that in the SCNT group. These results indicate that CICT helps improve the in vitro developmental competence and quality of cloned embryos.

Abstract
Somatic cell nuclear transfer (SCNT) is a useful technology; however, its efficiency is low. In this study, we investigated the effects of cytoplasmic transfer into enucleated oocytes on the developmental competence and quality of cloned preimplantation bovine embryos via terminal deoxynucleotidyl transferase dUTP nick-end labeling, quantitative reverse transcription PCR, and immunocytochemistry. We used cytoplasm injection cloning technology (CICT), a new technique via which the cytoplasmic volume of an enucleated oocyte could be restored by injecting ∼30% of the cytoplasm of a donor oocyte. The percentages of embryos that underwent cleavage and formed a blastocyst were significantly higher (p < 0.05) in the CICT group than in the SCNT group (28.9 ± 0.8% vs. 20.2 ± 1.3%, respectively). Furthermore, the total cell number per day 8 blastocyst was significantly higher in the CICT group than in the SCNT group (176.2 ± 6.5 vs. 119.3 ± 7.7, p < 0.05). Moreover, CICT increased mitochondrial activity, as detected using MitoTracker® Green. The mRNA levels of DNA methyltransferase 1 and DNA methyltransferase 3a were significantly lower (p < 0.05) in the CICT group than in the SCNT group. The mRNA level of DNA methyltransferase 3b was lower in the CICT group than in the SCNT group; however, this difference was not significant (p > 0.05). Taken together, these data suggest that CICT improves the in vitro developmental competence and quality of cloned bovine embryos.

Abstract
Acquisition of proper metabolomic fate is required to convert somatic cells toward fully reprogrammed pluripotent stem cells. The majority of induced pluripotent stem cells (iPSCs) are partially reprogrammed and have a transcriptome different from that of the pluripotent stem cells. The metabolomic profile and mitochondrial metabolic functions required to achieve full reprogramming of somatic cells to iPSC status have not yet been elucidated. Clarification of the metabolites underlying reprogramming mechanisms should enable further optimization to enhance the efficiency of obtaining fully reprogrammed iPSCs. In this study, we characterized the metabolites of human fully reprogrammed iPSCs, partially reprogrammed iPSCs, and embryonic stem cells (ESCs). Using capillary electrophoresis time-of-flight mass spectrometry-based metabolomics, we found that 89% of analyzed metabolites were similarly expressed in fully reprogrammed iPSCs and human ESCs (hESCs), whereas partially reprogrammed iPSCs shared only 74% similarly expressed metabolites with hESCs. Metabolomic profiling analysis suggested that converting mitochondrial respiration to glycolytic flux is critical for reprogramming of somatic cells into fully reprogrammed iPSCs. This characterization of metabolic reprogramming in iPSCs may enable the development of new reprogramming parameters for enhancing the generation of fully reprogrammed human iPSCs.

Abstract
Hepatocyte transplantation has been used to treat liver disease. The availability of cells for these procedures is quite limited. Human embryonic stem cells (hESCs) and induced pluripotent stem cells (hiPSCs) may be a useful source of hepatocytes for basic research and transplantation if efficient and effective differentiation protocols were developed and problems with tumorigenicity could be overcome. Recent evidence suggests that the cell of origin may affect hiPSC differentiation. Thus, hiPSCs generated from hepatocytes may differentiate back to hepatocytes more efficiently than hiPSCs from other cell types. We examined the efficiency of reprogramming adult and fetal human hepatocytes. The present studies report the generation of 40 hiPSC lines from primary human hepatocytes under feeder-free conditions. Of these, 37 hiPSC lines were generated from fetal hepatocytes, 2 hiPSC lines from normal hepatocytes, and 1 hiPSC line from hepatocytes of a patient with Crigler-Najjar syndrome, type 1. All lines were confirmed reprogrammed and expressed markers of pluripotency by gene expression, flow cytometry, immunocytochemistry, and teratoma formation. Fetal hepatocytes were reprogrammed at a frequency over 50-fold higher than adult hepatocytes. Adult hepatocytes were only reprogrammed with six factors, while fetal hepatocytes could be reprogrammed with three (OCT4, SOX2, NANOG) or four factors (OCT4, SOX2, NANOG, LIN28 or OCT4, SOX2, KLF4, C-MYC). The increased reprogramming efficiency of fetal cells was not due to increased transduction efficiency or vector toxicity. These studies confirm that hiPSCs can be generated from adult and fetal hepatocytes including those with genetic diseases. Fetal hepatocytes reprogram much more efficiently than adult hepatocytes, although both could serve as useful sources of hiPSC-derived hepatocytes for basic research or transplantation.
