[ 1 ] - تأثیر کلاژن بر سنتز نانوذرات کلسیم فسفات
کلاژن و ترکیبات کلسیم فسفاتی، بویژه نانوهیدروکسی آپاتیت ترکیبات اصلی استخوان طبیعی هستند. در سنتز همزمان هیدروکسی آپاتیت در حضور کلاژن، ذرات کلسیم فسفات در امتداد فیبریل کلاژن رشد کرده؛ میکروساختار متفاوتی را ایجاد می‌کنند. از این رو تأثیر کلاژن بر ویژگی‌های میکروساختاری و فازی ذرات کلسیم فسفات، بررسی شد. با توجه به سنتز همزمان هیدروکسی آپاتیت در حضورکلاژن، کلرید کلسیم به عنوان ...
[ 2 ] - Mesenchymal Stem Cells Derived from Rat Epicardial Versus Epididymal Adipose Tissue
Objective(s) Some investigation has indicated that adipose-derived stem cells possess different surface epitopes and differentiation potential according to the localization of fat pad from which the cells were derived. In the present study proliferation capacity and aging of such cells were explored. Materials and Methods Adherent cells were isolated from the collagenase digests of adipose tiss...
[ 3 ] - Study of telomerase activity, proliferation and differentiation characteristics in umbilical cord blood mesenchymal stem cells
In recent years, considerable advances have been made in the field of regenerative medicine. Unlikeembryonic stem cells, which pose the problems of ethical concerns and cause severe immunological reactions as well as neoplasma formation after transplantation, umbilical cord blood is a primitive source ofmesenchymal stem cells that covers the benefits of both embryonic and adult stem cells. It h...
[ 4 ] - Equine marrow-derived mesenchymal stem cells: isolation, differentiation and culture optimization
Most studies regarding the marrow-derived equine mesenchymal stem cells (MSCs) have mainly focusedon the cell transplantation without considering the capacity of differentiation and in vitro requirements of thecells. These concerns were investigated in the present study. Equine MSCs were isolated from the sternalmarrow aspirates and expanded through two successive subcultures. Passage-2 equine ...
[ 5 ] - Effects of BIO on proliferation and chondrogenic differentiation of mouse marrow-derived mesenchymal stem cells
In vitro expansion of mesenchymal stem cell (MSCs) into large number is necessary for their application in cell-based treatment of articular cartilage defects. On the other hand, some studies have indicated that BIO (6-Bromoindirubin-3-Oxime) possesses mitogenic effects on cell culture. The objective of the present study was to examine the effect of BIO on in vitro expansion and chondrogenic di...
[ 6 ] - Blastema from rabbit ear contains progenitor cells comparable to marrow derived mesenchymal stem cells
Rabbits have the capacity to regenerate holes in their ears by forming a blastema, a tissue that is made up of a group of undifferentiated cells. The purpose of the present study was to isolate and characterize blastema progenitor cells and compare them with marrow mesenchymal stem cells (MSCs). Five New Zealand white male rabbits were used in the present study. A 2-mm hole was created in the a...
[ 7 ] - بررسی سلول‌های بنیادی مزانشیمی مشتق از دیواره ورید ناف انسانی و تعیین روند تمایز آن به غضروف و استخوان
زمینه: سلول‌های بنیادی مزانشیمی شامل پیش‌سازهای چندظرفیتی نادری هستند که قادر به تمایز به دودمان‌های استخوان‌ساز، چربی‌ساز، غضروف‌ساز می‌باشند. به‌دلیل این توانایی‌ها، به‌نظر می‌رسد که سلول‌های بنیادی مزانشیمی به ابزاری مورد توجه در چرخه مهندسی بافت و سلول درمانی تبدیل شده‌اند. هدف از این مطالعه استفاده از بند ناف به‌عنوان یک منبع در دسترس سلول‌های بنیادی مزانشیمی بوده است. مواد و روش‌ها: در ای...
[ 8 ] - مطالعه تاثیر بایو [6-bromoindirubin-3?-oxim (BIO)] برتکثیر و تمایز به استخوان سلول های بنیادی مزانشیمی مشتق از مغز استخوان موش صحرایی
Introduction & Objective: According to some study, wnt signaling pathway is among those molecular pathways that involve in cellular proliferation and bone differentiation. On the other hand, investigations have indicated that 6-bromoindirubin-3´-oxim (BIO) is able to activate this pathway. In the present study, effect of BIO on in vitro proliferation and bone differentiation of mesenchymal ...
[ 9 ] - Quantitative Analysis of the Proliferation and Differentiation of Rat Articular Chondrocytes in Alginate 3D Culture
Background: While articular chondrocytes are among those appropriate candidates for cartilage regeneration, the cell dedifferentiation during monolayer culture has limited their application. Several investigations have indicated the usefulness of alginate, but the topic of proliferation and differentiation of chondrocytes in alginate culture has still remained controversial. Methods: Rat articu...
[ 10 ] - Growth Kinetics and in Vitro Aging of Mesenchymal Stem Cells Isolated From Rat Adipose Versus Bone Marrow Tissues
Objective- To investigate and compare growth potential as well as aging of mesenchymal stem cells (MSCs) derived from rat bone marrow tissue and adipose tissue (AT) occurred at epicardial and epididymal regions. Design- Experimental study. Animals- 10 Wistar Rats. Procedures- Rat MSCs occurred at bone marrow and epicardial and epididymal AT were isolated and culture expanded through sev...
[ 11 ] - Enhancing Ectopic Bone Formation in Canine Masseter Muscle by Loading Mesenchymal Stem Cells onto Natural Bovine Bone Minerals.
Objectives- To assess the ectopic bone formation in canine masseter muscle following the implantation of the natural bovine bone minerals (NBM) loaded with canine mesenchymal stem cells (MSCs).Design- Experimental study.Animals- four mongrel dogs.Procedures- Tripotent MSCs isolated from the canine bone marrow were loaded onto the NBM sponges and allowed to adhere. The cell-loaded scaffolds were...
[ 12 ] - A novel inexpensive method for preparation of silk nanofibers from cocoons
AbstractIn the present study , a novel method for the production of silk nano fibers are presented . In this way , a mechanical and easy technique is used instead of toxic and costly chemical methods . Also , the separation of silk nano fibers from the cocoon was carried out by mechanical homogenizer and probe ultrasonic homogenizer . After the preparation of silk nanofibers , the product was c...
[ 13 ] - Small Molecule-BIO Accelerates and Enhances Marrow-Derived Mesenchymal Stem Cell in Vitro Chondrogenesis
Background: Hyaline cartilage defects exhibit a major challenge in the field of orthopedic surgery owing to its limited repair capacity. On the other hand, mesenchymal stem cells (MSCs) are regarded as potent cells with a property of cartilage regeneration. We aimed to optimize marrow-derived MSC chondrogenic culture using a small bioactive molecule referred to as BIO. Methods: MSCs from the ma...
