Dentre todas as células-tronco estudadas até o presente momento, mesenquimais (MSC) destacam-se por sua elevada plasticidade, podendo originar tecidos mesodermais e não mesodermais. Além disso, possuem características imunomoduladoras imunossupressoras que ampliam possibilidades de utilização terapêutica. As MSC secretam uma grande variedade citocinas pró anti-inflamatórias fatores crescimento e, meio dessas moléculas bioativas, proporcionam a modulação da resposta inflamatória,...
This article details the in situ preparation of composite scaffolds using polyurethane (PU) and HAp (hydroxyapatite), focusing on unique properties buriti oil (Mauritia flexuosa L.) applicable to tissue engineering. PU derived from vegetable oils, particularly oil, has shown promise bone repair due its rich bioactive compounds. Buriti is an excellent candidate for manufacturing these materials as it compounds such carotenoids, tocopherols, fatty acids, which have antioxidant...
ABSTRACT Introduction/Objectives: Agoutis is a medium‐sized wild rodent with potential for use as an experimental model. This study aimed to evaluate physiological parameters of arrhythmogenesis in this species, by HR‐ECG and VCG techniques, under physical pharmacological containment (ketamine‐xylazine butorphanol). Materials methods: Eight agouti which the were evaluated containment. We cardiac pulmonary foci sounds, made femoral pulse inspection, body score analysis, gestational...
Hydrogels are structures that have value for application in the area of tissue engineering because they mimic extracellular matrix. Naturally obtained polysaccharides, such as chitosan (CH) and cashew gum, materials with ability to form polymeric networks due their physicochemical properties. This research aimed develop a scaffold based on phthalated tree gum test it support growth human mesenchymal stem cells. In this study, phthalation (PCG) was performed by using solvent-free route....

Hydrogels from natural sources are attracting increasing interest due to their ability protect biologically active molecules. Starch extracted cassava tubers is a promising material for synthesizing these hydrogels. Copolymerization of gum and incorporation chlorhexidine digluconate (CLX) into the hydrogels confirmed by changes in crystallographic profile, as observed through X-ray diffraction, shift 1000 cm
Mesenchymal stem cells have been widely used in the treatment of various chronic diseases. The objective this survey was to evaluate therapeutic and regenerative potential from adipose tissue (ASCs) milk production recovery repair injury mastitis goats treated with antimicrobial agents prior cell therapy. After diagnosis gentamicin, eight lactating were selected for cellular subsequent therapy, physical-chemical analysis milk, ultrasonographic histopathological examinations. ASCs taken...
PURPOSE: To evaluate the effects of mesenchymal stem cells (MSC) from eight mice C57BL/6 gfp+ bone marrows expanded in cultures associated with platelets rich plasma (PRP) deriving another mice, repair critical defects calvarial produced twenty-four adult isogenic C57BL/6. METHODS: The animals were submitted to a cranial defect 6.0mm diameter and divided into two equal experimental groups. Control group did not receive treatment treated received MSC pellet containing 1.0 x 10(7) cells/mL...
Purpose: To assess the efficacy of allogeneic mesenchymal stem cells and xenogenic platelet rich plasma in treatment bone failure osteoporotic rabbits secondary to estrogenic deprivation iatrogenic hypercortisolism. Methods: Eight female underwent ovarian resection corticoid therapy induce clinical status osteoporosis. Four failures were produced tibiae, with each being treated hemostatic sponge, allogenic cells, platelet-rich association between both. The animals divided into two groups,...
Background: There are few studies on stem cell isolation in wild animals that provide and culture protocols of these cells vitro. Among the species studied, we present collared peccary (Tayassu tajacu) as a model with potential to obtain use MSC preclinical studies. These phylogenetically close domestic pig, popularly known peccaries found naturally South America, Central America United States. The aim study was establish protocol for isolation, vitro expansion, differentiation assessment...
Tissue engineering aims to recreate natural cellular environments facilitate tissue regeneration. Gelatin methacrylate (GelMA) is widely utilized for its biocompatibility, ability support cell adhesion and proliferation, adjustable mechanical characteristics. This study developed a GelMA graphene bioink platform at concentrations of 1, 1.5, 2 mg/mL enhance scaffold properties applications.
To produce polysaccharide-based hydrogels and cerium (Ce3+) doped hydroxyapatite plus chitosan collagen to enable future applications in the treatment of joint degeneration.

Mesenchymal stem cells (MSC) are present in specialized niches perivascular regions of adult tissues and able to differentiate into various cell types, such as those committed repairing. Bone marrow derived MSC from eight young mice C57BL/ 6 gfp(+) were expanded culture for repairing critical defects calvarial bone produced twenty-four isogenic C57BL/6 mice. The animals subjected a cranial defect 6.0mm diameter divided two equal experimental groups. Control group did not receive any...

Introduction: Wound healing is a progressive, essential and complex physiological process that occurs as restorative response after tissue injury. It involves three phases: inflammation, proliferation maturation. Exogenous, endogenous pathological factors may interfere in the cicatricial humans animals by altering balance between synthesis, degradation remodelling of collagen elastic fibres. Diabetes mellitus progressive metabolic disease alters elastogenesis collagenesis induces delays...
