Transcriptional Profliing of small molecules induced endothelial cells of stem cells from apical papilla (SCAP-ECs), stem cells from apical papilla (SCAP) and human vein endothelial cells (HUVECs)

Project description:Recently, a new strategy has been developed to directly reprogram one cell type towards targeted cell type by using different combinations of small molecule compounds. Here we attempted to induce stem cells from apical papilla (SCAP) into endothelial cells (ECs) by the same strategy. We developed a set of small molecules and growth factors that facilitates the conversion of SCAP into stable endothelial lineage. The SCAP-derived endothelial cells (SCAP-ECs) expressed some up-regulated endothelial specific genes and proteins, exhibited the ability to form functional tubular-like structures in vitro, and contributed to generate blood vessels in vivo. The aim of this study is to compare the ECs-related gene profile of SCAP, SCAP-derived ECs and HUVECs (primary ECs) and to explore whether SCAP-derived ECs showed enriched ECs gene expression.

Expression data of microRNA from human stem cells from apical papilla

Project description:Osteo/odontogenic differentiation is a key process of human stem cells from apical papilla (SCAP) in tooth root development. Emerging evidence indicates microRNAs (miRNAs) play diverse roles in osteogenesis. However, their functions in osteo/odontogenic differentiation of SCAP remain to be elucidated. We used miRNA microarray to analysis differentially expressed miRNAs in order to investigate the role of miRNAs in SCAP osteo/odontogenic differentiation and underlying mechanism.

The human dental apical papilla promotes spinal cord repair through a paracrine mechanism

Project description:Traumatic spinal cord injury is an overwhelming condition that strongly and suddenly impacts the patient’s life and her/his entourage. There are currently no predictable treatments to repair the spinal cord, while many strategies are proposed and evaluated by researchers throughout the world. One of the most promising avenues is the transplantation of stem cells, although its therapeutic efficiency is limited by several factors, among which cell survival at the lesion site. In our previous study, we showed that the implantation of a human dental apical papilla, residence of stem cells of the apical papilla (SCAP), supported functional recovery in a rat model of spinal cord hemisection.

Impact of a pro-inflammatory stimulus on the miRNA composition of extracellular vesicles (EV) from stem cells from apical papilla (SCAP)

Project description:To investigate the impact of a pro-inflammatory stimulus (TNFα and IFNγ, 20 ng/ml) on miRNA in SCAP-EV, we isolated EV from non-activated and activated SCAP and then extracted miRNA

Deletion of Scap in Alveolar Type II Cells Influences Lung Lipid Homeostasis and Identifies a Compensatory Role for Pulmonary Lipofibroblasts

Project description:Pulmonary function after birth is dependent upon surfactant lipids that reduce surface tension in the alveoli. The sterol-responsive element-binding proteins (SREBPs) are transcription factors regulating expression of genes controlling lipid homeostasis in many tissues. To identify the role of SREBPs in the lung, we conditionally deleted the SREBP cleavage-activating protein gene, Scap, in respiratory epithelial cells (Scap∆/∆) in vivo. Prior to birth (E18.5), deletion of Scap decreased the expression of both SREBPs and a number of genes regulating fatty acid and cholesterol metabolism. Nevertheless, Scap∆/∆ mice survived postnatally, surfactant and lung tissue lipids being substantially normalized in adult Scap∆/∆ mice. Although phospholipid synthesis was decreased in type II cells from adult Scap∆/∆ mice, lipid storage, synthesis, and transfer by lung lipofibroblasts were increased. mRNA microarray data indicated that SCAP influenced two major gene networks, one regulating lipid metabolism and the other stress-related responses. Deletion of the SCAP/SREBP pathway in respiratory epithelial cells altered lung lipid homeostasis and induced compensatory lipid accumulation and synthesis in lung lipofibroblasts. To identify the role of SREBPs in the lung, we conditionally deleted the SREBP cleavage-activating protein gene, Scap, in respiratory epithelial cells (Scap∆/∆) in vivo.Lung cRNA was hybridized to the murine genome MOE430 V2 chips.

microRNA profile of extracellular vesicles derived from control vehicle- and LIPUS-induced stem cells from the apical papilla

Project description:Low intensity pulsed ultrasound (LIPUS) is shown to promote osteogenic differentiation and antiinflammation of periodontal mesenchymal stromal cells. We found extracellular vesicles (EVs) derived from LIPUS-induced stem cells from apical papilla (SCAPs) also have stronger anti-inflammatory and osteogenic effects in vitro and in vivo. To obtain clues on whether microRNA (miR) of EVs contribute to stronger anti-inflammatory and osteogenic effects, we analyzed miR expression in EVs from control- and LIPUS-induced SCAPs by deep sequencing. RNA-sequencing suggests that the LIPUS-EVs induce stronger osteogenic differentiation and antiinflammation by using their cargos, including upregulated osteogenic miRNAs to activate the PI3K/Akt and MAPK signaling pathways, and upregulated anti-inflammatory miRNAs to inhibit the TNF-α signaling pathways.

snRNA-seq analysis of apical-out endometrial organoids including endometrial stromal cells and human umbilical vein endothelial cells

Project description:In this study, we developed an apical-out-endometrial organoids (AO-EMO + eSC/HUVEC), which exposes the apical surface of the epithelium and contains eSC and an endothelial network. To evaluate this model, we conducted a single-nucleus RNA-sequencing (snRNA-seq).

Global profiling of human hair follicle scalp dermal papilla cells using Affymetrix microarrays

Project description:Dermal papilla cells isolated from the human hair follicle are capable of inducing hair growth in recipient epithelia. However, demonstrating disparity from rodent dermal papilla, human cells lose this inductive competance immediately upon growth in culture under normal growth conditions. We grew dermal papilla cells in hanging drop cultures that are morphologically akin to intact dermal papilla, and found that by enhancing the environment for aggregation, we could restore the inductive capacity of human dermal papilla cells in culture. The underlying genes that regulate the inductive potential of dermal papilla cells is not well understood, and we sought to use global profiling to identify key genes and pathways related to inductive competance within dermal papilla cells. We used Affymetrix microarrays to profile human dermal papilla cells in both hair inducing, and non-hair inducing states. Affymetrix microarrays were used to to perform profiling of human dermal papilla cells, both as intact tissues (freshly isolated from scalp), and at several stages in subsequent two dimensional culture; cell explant outgrowths (p0), cells at passage 1 (p1), passage 3 (p3) and passage 5 (p5). RNA was isolated from cultured cells 72 hours after feeding. Cells at passage 3 were also grown in hanging drops to form dermal spheroids, that were used for RNA collection 48 hours after establishment. All experiments were performed using tissue from three biological replicates (#D5, D6, D7),
