Abstract
Radiation enteritis is the most common and serious complication of abdominal or
pelvic radiation therapy. Mesenchymal stem cells (MSCs), as well as cell
protection agents, inhibit apoptosis and promote the proliferation of injured
tissues. 3 human umbilical cords MSCs (UCMSCs) were injected into the tail vein
or peritoneal cavity of a rat model of radiation enteritis. The temporary
protective effect was assessed by identification of donor cells, detection of
cellular immune parameters and inflammatory cytokine levels, quantitation of
jejunum mucosal preservation and examination of the rat remaining life. Only the
rats in the intraperitoneal injection group exhibited a few positive donor cells
7 days after transplantation. CD4+/CD8+ T cells, a cellular immune parameter, decreased in the abdominal
exudate of intraperitoneal injection group, compared with the model-only control
and tail vein groups (both P < .05). Both serum and
abdominal exudate TNF-α and IL-6 levels in the intraperitoneally injected rats
rapidly decreased and were significantly different from those in the model-only
control and tail vein injection groups (all P < .05).
Mucosal surface area and survival time increased in the intraperitoneal
injection group compared with the vehicle and tail vein injection groups (all
P = .000). Therefore, the administration of UCMSCs with
intraperitoneal injection approach postponed death in a rat model of radiation
enteritis, which was associated with reduced serum levels of proinflammatory
cytokines (TNF-α, IL-6). However, UCMSCs injected via the tail vein triggered an
intense cellular immune response in the serum that adversely affects their
survival. This treatment failed to suppress circulating serum and abdominal
exudate levels of TNF-α and IL-6 and could not provide a therapeutic benefit for
prolonging life against acute radiation enteritis.

Identification and comparison of novel circular RNAs with associated co-expression and competing endogenous RNA networks in postmenopausal osteoporosis. J Orthop Surg Res 2021; 16:459. [PMID: 34271965 PMCID: PMC8285836 DOI: 10.1186/s13018-021-02604-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 07/07/2021] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Circular RNAs (circRNAs) are emerging as crucial regulators in various human diseases. So far, the expression profile and regulatory mechanism of circRNAs in postmenopausal osteoporosis (PMOP) are less studied and should be deciphered urgently. Herein, we aimed to reveal key circRNAs affecting PMOP and clarify their compounding regulatory actions. METHODS To reveal key circRNAs affecting PMOP and clarify their compounding regulatory actions, whole transcriptome sequencing and bioinformatics analysis were performed to identify differentially expressed circRNAs (DECs). The expression pattern and regulatory networks of DECs in peripheral blood mononuclear cells (PBMCs) were unearthed. RESULTS A total of 373 DECs comprising 123 intronic, 100 antisense, 70 exonic, 55 intergenic, and 25 sense-overlapping circRNAs were identified. Among these, 73 circRNAs were upregulated and 300 were downregulated. These DECs exerted pivotal functions in the pathogenesis of PMOP as demonstrated by Gene Ontology (GO) annotation and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. The circRNA-miRNA-mRNA co-expression network comprising 28 DECs, 145 miRNAs, and 175 differentially expressed mRNAs predicted the possible mechanism of the pathogenesis and progression of PMOP. CONCLUSION The results of the present study provided a further comprehension of circRNA-associated competing endogenous RNA regulatory mechanism in PMOP. The steadily expressed and disease-specific DECs may serve as promising diagnostic and prognostic biomarkers for PMOP.

Abstract
OBJECTIVES Current treatments for osteoporosis were prevention of progression, yet it has been questionable in the stimulation of bone growth. The mesenchymal stem cells (MSCs) treatment for osteoporosis aims to induce differentiation of bone progenitor cells into bone-forming osteoblasts. We investigate whether human umbilical cord blood (hUCB)-MSCs transplantation may induce bone regeneration for osteoporotic rat model induced by ovariectomy. METHODS The ovariectomized (OVX) group (n = 10) and OVX-MSCs group (n = 10) underwent bilateral ovariectomy to induce osteoporosis, while the Sham group (n = 10) underwent sham operation at aged 12 weeks. After a femoral defect was made at 9 months, Sham group and OVX group were injected with Hartmann solution, while the OVX-MSCs group was injected with Hartmann solution containing 1 × 107 hUCB-MSCs. The volume of regenerated bone was evaluated using micro-computed tomography at 4 and 8 weeks postoperation. RESULTS At 4- and 8-week postoperation, the OVX group (5.0% ± 1.5%; 6.1% ± 0.7%) had a significantly lower regenerated bone volume than the Sham group (8.6% ± 1.3%; 12.0% ± 1.8%, P < 0.01), respectively. However, there was no significant difference between the OVX-MSCs and Sham groups. The OVX-MSCs group resulted in about 53% and 65% significantly higher new bone formation than the OVX group (7.7% ± 1.9%; 10.0% ± 2.9%, P < 0.05). CONCLUSIONS hUCB-MSCs in bone defects may enhance bone regeneration in osteoporotic rat model similar to nonosteoporotic bone regeneration. hUCB-MSCs may be a promising alternative stem cell therapy for osteoporosis.

Abstract
As a type of osteoporosis (OP), male idiopathic OP (MIO) is a bone disorder that occurs in young males and is a public health problem worldwide. However, the detailed pathogenesis of MIO remains to be elucidated. In the present study, blood samples of patients with MIO, senile OP, postmenopausal OP and normal controls (NCs) were obtained for RNA sequencing. Compared with the NC group, differentially expressed genes (DEGs) in the three types of OP were identified. DEGs that were common among the three types of OP and the DEGs that were unique to patients with MIO were determined. Gene ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were conducted. MIO‑specific and OP‑specific protein‑protein interaction (PPI) networks were constructed. Compared with NCs, a total of 519, 368 and 1,472 DEGs were identified in samples from MIO, senile OP and postmenopausal OP, respectively. Tetraspanin 5 (TSPAN5) and α‑synuclein (SNCA) were unique DEGs in MIO that were not identified in the other two types of OP compared with NCs. Furthermore, the expression of carbonic anhydrase 1 (CA1) and S100 calcium‑binding protein P (S100P) in MIO was significantly different compared with senile OP, postmenopausal OP and NC samples. 'MAPK signaling pathway', 'type I diabetes mellitus' and 'hematopoietic cell lineage' were among significantly enriched pathways of DEGs in MIO. SNCA and CDC‑like kinase 1 were the hub genes in the MIO‑specific PPI network. In conclusion, the mitogen‑activated protein kinase signaling and type I diabetes mellitus pathways may be involved in bone formation; SNCA and TSPAN5 may be associated with bone resorption. These two pathways and two genes may serve a role in MIO. CA1 and S100P may regulate the process of MIO by modulation of calcification and dysregulation of calcium binding. These findings may have provided an experimental basis for elucidating the underlying mechanisms and developing potential diagnostic biomarkers of MIO.

Multiplacenta derived stem cell/cytokine treatment increases survival time in a mouse model with radiation-induced bone marrow damage. Cytotechnology 2016; 68:2677-2686.

Abstract
Nuclear Warfare and nuclear leakage can result in a large number of patients with radiation-induced bone marrow damage. Based on the fact that hematopoietic stem cells and hematopoietic growth factors are characterized as a novel strategy for therapy, the aim of this study was to explore a safe and routine stem cell/cytokine therapeutic strategy. Allogeneic multiplacenta derived hematopoietic and mesenchymal stem cells/cytokines were intraperitoneally injected into a moderate dose of total body irradiation-induced mouse bone marrow damage model a single time. Then, the mouse posttransplantation survival time, peripheral blood hemoglobin count, bone marrow architecture, and donor cell engraftment were assessed. Each mouse that received placenta-derived stem cells exhibited positive donor hematopoietic and mesenchymal stem cell engraftment both in the bone marrow and peripheral blood after transplantation. The peripheral blood hemoglobin count and survival time were greater in the group with the combined treatment of multiplacenta-derived stem cells and cytokines, compared with model-only controls (both P < 0.001). The blood smear mesenchymal/hematopoietic stem cell count was significantly higher in the combined treatment group than in the mice treated only with placenta-derived cells (28.08 ± 5.824 vs. 20.40 ± 5.989, P < 0.001; 7.74 ± 2.153 vs. 4.23 ± 1.608, P < 0.001, respectively). However, there was no marked change on the bone marrow pathology of any of the experimental mice after the transplantation. These results indicate that for radiation-induced bone marrow damage treatment, multiplacenta-derived stem cells and cytokines can increase the life span of model mice and delay but not abrogate the disease progression. Intraperitoneally transplanted stem cells can survive and engraft into the host body through the blood circulation. Improvement of peripheral blood hemoglobin levels, but not the bone marrow architecture response, probably explains the increase in survival time observed in this study.

Abstract
Coinfusion of hematopoietic and mesenchymal stem cells is more effective than hematopoietic stem cell transplantation alone. It is necessary to explore a safe and routine mixed stem cell intraperitoneal transplantation method. Multiplacentas pooled cells were intraperitoneally injected into a radiation- and immunity-induced mouse aplastic anemia model with single time. Then, mouse survival time, peripheral blood hemoglobin count, bone marrow architecture, and donor cell engraftment were assessed. The recipient mouse exhibited donor cell engraftment in both bone marrow and peripheral blood. Survival time and peripheral blood hemoglobin count increased in placenta pooled cells treated mice, compared with model-only controls (P = 0.048 and P = 0.000, resp.). However, placentas pooled cells failed to cause a significant decrease in bone marrow pimelosis area (P = 0.357). Intraperitoneally transplanted multiplacentas pooled cells can survive and engraft into a host body through blood circulation, which can increase the life span of an aplastic anemia model mice, and delay but not abrogate the development of aplastic anemia. Furthermore, they appear to play a role in increasing peripheral blood hemoglobin level response for increasing the life span of aplastic anemia model mice.

Abstract
As the worldwide population grows and life expectancies continue to increase, degenerative diseases of the bones, muscles, and connective tissue are a growing problem for society. Current therapies for osteodegenerative disorders such as hormone replacement therapies, calcium/vitamin D supplements and oral bisphosphonates are often inadequate to stop degeneration and/or have serious negative side effects. Thus, there is an urgent need in the medical community for more effective and safer treatments. Stem cell therapies for osteodegenerative disorders have been rigorously explored over the last decade and are yielding some promising results in animal models and clinical trials. Although much work still needs to be done to ensure the safety and efficacy of these therapies, stem cells represent a new frontier of exciting possibilities for bone and cartilage regeneration.
