13. Cytokine expression patterns and mesenchymal stem cell karyotypes from the bone marrow microenvironment of patients with myelodysplastic syndromes
The purpose of this study was to explore cytokine expression patterns and cytogenetic abnormalities of mesenchymal stem cells (MSCs) from the bone marrow microenvironment of Chinese patients with myelodysplastic syndromes (MDS). Bone marrow samples were obtained from 30 cases of MDS (MDS group) and 30 healthy donors (control group). The expression pattern of

14. Isolation and characterization of mesenchymal progenitors derived from the bone marrow of goats native from northeastern Brazil
PURPOSE:To characterize bone marrow progenitors cells grown in vitro,using native goats from northeastern Brazil as animal model.METHODS:Ten northeastern Brazil native goats of both genders were used from the Piauí Federal University Agricultural Science Center's (UFPI) - Goat Farming Sector. Bone marrow aspirates where taken from the tibial ridge and seede

15. Overexpression of hsa-miR-125b during osteoblastic differentiation does not influence levels of Runx2, osteopontin, and ALPL gene expression
Multipotent mesenchymal stromal cells (MSCs) were first isolated from bone marrow and then from various adult tissues including placenta, cord blood, deciduous teeth, and amniotic fluid. MSCs are defined or characterized by their ability to adhere to plastic, to express specific surface antigens, and to differentiate into osteogenic, chondrogenic, adipogenic

16. Regeneração do ramo mandibular do nervo facial de ratos após a implantação de células multipotentes do estroma mesenquimal indiferenciadas e diferenciadas in vitro que apresentam fenótipo de células de Schwann / Regenereation of the mandibular branch of rats\ facial nerve regenereation after implanting undifferenciated mesenchymal stromal multipotent cells and differenciated Schwann-like cells in vitro
INTRODUÇÃO: O nervo facial desempenha um papel importante em diversas funções fisiológicas no organismo, no entanto, distúrbios funcionais desse nervo podem também afetar a psique do indivíduo, provocando mudanças significativas na autoimagem, interferindo no rendimento profissional e piorando a qualidade de vida. Lesões graves do nervo facial (neu

17. In vitro cultivation of canine multipotent mesenchymal stromal cells on collagen membranes treated with hyaluronic acid for cell therapy and tissue regeneration
Support structures for dermal regeneration are composed of biodegradable and bioresorbable polymers, animal skin or tendons, or are bacteria products. The use of such materials is controversial due to their low efficiency. An important area within tissue engineering is the application of multipotent mesenchymal stromal cells (MSCs) to reparative surgery. The

18. Estudo sobre condições do cultivo de células-tronco mesenquimais para aplicações clínicas
Introdução: Células-troco mesenquimais (CTM) vêm mostrando seus benefícios na doença do enxerto-versus-hospedeiro (DECH), observada no transplante de células tronco hematopoéticas (TCTH), existem três questões em aberto: (1) Expansão de CTM em meio de cultura suplementado com soro fetal bovino (SFB), pelo o risco de xenorreação; (2) Otimização

19. Potencial terapêutico do transplante xenogênico de células mesenquimais estromais na Doença Inflamatória Intestinal. / Therapeutic potential of xenogenic mesenchymal stromal cells transplantation in inflammatory bowel disease.
As Doenças Inflamatórias Intestinais (DII), como a doença de Crohn e a colite ulcerativa, são caracterizadas por inflamação crônica descontrolada da mucosa intestinal. Enquanto a colite ulcerativa apresenta-se com resposta Th2, pacientes com doença de Crohn apresentam resposta Th1 e, recentemente, descobriu-se a presença de células Th17 na mucosa i

20. "Influência da composição de carreador biodegradável na viabilidade do implante de células mesenquimais indiferenciadas do tecido adiposo humano" / Influence of scaffold composition in the viability of implantation of human adipose derived undifferentiated mesenchymal cells
Human undifferentiated mesenchymal cells were obtained by enzymatic digestion and centrifugation of the product of liposuction. These cells were expanded, in vitro, and implanted subcutaneously in athymic mice. In group I, each animal received the implant of a 0,25cm2 membrane of glycolic acid and trimethylene carbonate, seeded with 1 x 106 of these cells. I

21. Efeito inibidor da finasterida sobre a enzima 5-alfa-redutase na prostata de gerbilos adultos (Meriones unguiculatus)
Prostatic deve1opment and differentiatíon are induced by androgens acting via mesenchymal-epithelial interactions, and during adult life the gland is maintained functionally active by reciprocal homeostatic stromal-epithelial interactions. Hormonal alterations, usually associated with the physical aspects of aging, leads to disruptions of this homeostatic i

22. Tumor estromal gastrointestinal de intestino delgado
Stromal tumors of the gastrointestinal tract (gists) represent relatively rare lesions that arise from connective tissue elements located along the entire length of the gut. They were initially identified by immunohistochemical investigation, proving their origin from nondifferentiated mesenchymal cells. Only a minority of this lesions, mainly those confined

23. Bone Marrow Stromal Cells, Preadipocytes, and Dermal Fibroblasts Promote Epidermal Regeneration in Their Distinctive Fashions
Mesenchymal cell types, under mesenchymal-epithelial interaction, are involved in tissue regeneration. Here we show that bone marrow stromal cells (BMSCs), subcutaneous preadipocytes, and dermal fibroblasts distinctively caused keratinocytes to promote epidermal regeneration, using a skin reconstruction model by their coculture with keratinocytes. Three mese

24. Adamantinoma of long bones: clinical, pathological and ultrastructural features.
The clinical, pathological and ultrastructural features of two cases of tibial adamantinoma are described. Both lesions showed identical features with a mixed histological picture exhibiting baseloid, tubular and squamous differentiation and a prominent stromal (mesenchymal) component. By light microscopy there appeared to be an intimate relation between the
