Abstract
Cardiovascular diseases are the leading cause of global mortality, in which myocardial infarction accounts for 46% of total deaths. Although good progress has been achieved in medication and interventional techniques, a proven method to repair the damaged myocardium has not yet been determined. Stem cell therapy for damaged myocardial repair has evolved into a promising treatment for ischemic heart disease. However, low retention and poor survival of the injected stem cells are the major obstacles to achieving the intended therapeutic effects. Chinese botanical and other natural drug substances are a rich source of effective treatment for various diseases. As such, numerous studies have revealed the role of Chinese medicine in stem cell therapy for myocardial infarction treatment, including promoting proliferation, survival, migration, angiogenesis, and differentiation of stem cells. Here, we discuss the potential and limitations of stem cell therapy, as well as the regulatory mechanism of Chinese medicines underlying stem cell therapy. We focus on the evidence from pre-clinical trials and clinical practices, and based on traditional Chinese medicine theories, we further summarize the mechanisms of Chinese medicine treatment in stem cell therapy by the commonly used prescriptions. Despite the pre-clinical evidence showing that traditional Chinese medicine is helpful in stem cell therapy, there are still some limitations of traditional Chinese medicine therapy. We also systematically assess the detailed experimental design and reliability of included pharmacological research in our review. Strictly controlled animal models with multi-perspective pharmacokinetic profiles and high-grade clinical evidence with multi-disciplinary efforts are highly demanded in the future.

Potential role of active decompression with distraction sugosteogenesis for the management of odontogenic cystic lesions: a retrospective review of 10 cases. Oral Maxillofac Surg 2021; 26:239-245. [PMID: 34184162 DOI: 10.1007/s10006-021-00970-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 05/05/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE The aim of this paper is to describe active decompression and distraction sugosteogenesis as an alternative for the management of odontogenic cystic lesions. The technique, demographics, success rate, and complications will be presented. PATIENTS AND METHODS A retrospective case series study design was implemented. This included patients found in our database from 2015 to 2018 with a diagnosis of any odontogenic cyst, in whom active decompression with distraction sugosteogenesis was implemented. The patient's medical history, demographics, radiographic characteristics of the cyst, technique/device employed, complications, and rate of success were recorded. RESULTS The sample consisted of 10 patients, with a mean age of 19.6 years (range 14-34). Sixty percent of all cases occurred in male patients and 40% in females. Forty percent of cases were consistent with odontogenic keratocysts with all cysts presenting in the mandible. No maxillary cases were documented. Seventy percent of such lesions were unilocular and 30% multilocular. Cortical fenestration/perforation was documented in 30% of cases and 1 pathologic fracture was seen. Active decompression was performed for an average of 37 days (range 30-50 days). With this system, radiographic resolution occurred in 1-3 months in 50% of cases, 6-12 months in 30% of cases, and 12 months in 20% of cases. Mean follow-up was 24.3 months. No recurrence was documented. Complications included fistula development (2 cases), flap dehiscence (1 case), and the size of the intraoral unit. CONCLUSIONS This investigation reviewed the authors' 5-year experience employing active decompression with distraction sugosteogenesis for the management of odontogenic cystic lesions and showed that this is a reliable alternative for the management of odontogenic cysts.

Stem Cell Res Ther 2020; 11:476. [PMID: 33168086 PMCID: PMC7653780 DOI: 10.1186/s13287-020-01999-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Accepted: 10/26/2020] [Indexed: 11/18/2022] Open
Abstract
Background Dentigerous cyst (DC) is a bone destructive disease and remains a challenge for clinicians. Marsupialization enables the bone to regenerate with capsule maintaining, making it a preferred therapeutic means for DC adjacent to vital anatomical structures. Given that capsules of DC are derived from odontogenic epithelium remnants at the embryonic stage, we investigated whether there were mesenchymal stem cells (MSCs) located in DC capsules and the role that they played in the bone regeneration after marsupialization. Methods Samples obtained before and after marsupialization were used for histological detection and cell culture. The stemness of cells isolated from fresh tissues was analyzed by morphology, surface marker, and multi-differentiation assays. Comparison of proliferation ability between MSCs isolated from DC capsules before (Bm-DCSCs) and after (Am-DCSCs) marsupialization was evaluated by Cell Counting Kit-8 (CCK-8), fibroblast colony-forming units (CFU-F), and 5′-ethynyl-2′-deoxyuridine (EdU) assay. Their osteogenic capacity in vitro was detected by alkaline phosphatase (ALP) and Alizarin Red staining (ARS), combined with real-time polymerase chain reaction (RT-PCR) and immunofluorescence (IF) staining. Subcutaneous ectopic osteogenesis as well as cranial bone defect model in nude mice was performed to detect their bone regeneration and bone defect repairability. Results Bone tissue and strong ALP activity were detected in the capsule of DC after marsupialization. Two types of MSCs were isolated from fibrous capsules of DC both before (Bm-DCSCs) and after (Am-DCSCs) marsupialization. These fibroblast-like, colony-forming cells expressed MSC markers (CD44+, CD90+, CD31−, CD34−, CD45−), and they could differentiate into osteoblast-, adipocyte-, and chondrocyte-like cells under induction. Notably, Am-DCSCs performed better in cell proliferation and self-renewal. Moreover, Am-DCSCs showed a greater osteogenic capacity both in vitro and in vivo compared with Bm-DCSCs. Conclusions There are MSCs residing in capsules of DC, and the cell viability as well as the osteogenic capacity of them is largely enhanced after marsupialization. Our findings suggested that MSCs might play a crucial role in the healing process of DC after marsupialization, thus providing new insight into the treatment for DC by promoting the osteogenic differentiation of MSCs inside capsules.
