1. Amniotic membrane as a biological scaffold for dental pulp stem cell transplantation in ocular surface reconstruction
RESUMO Objetivos: Avaliar a capacidade das células-tronco imaturas da polpa do dente de leite que são células-tronco mesenquimais de origem da crista neural, de se diferenciarem no epitélio corneano para fins de transplante de córnea e engenharia de tecidos quando cultivadas em membrana amnióticas desepitelizadas. Métodos: Foram comparamos so imunof

2. Efficacy of stem cells on bone consolidation of distraction osteogenesis in animal models: a systematic review
Abstract Distraction osteogenesis (DO) relies on the recruitment and proliferation of mesenchymal stem cells (MSC) to the target site, where they differentiate into osteoblasts to promote bone formation. Nevertheless, MSC recruitment appears to be slow and limits bone formation in DO defects. Thus, this systematic review aims to evaluate the ability of local

3. 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

4. A influência da criopreservação nas células mesenquimais indiferenciadas do ligamento periodontal de humanos análise comparativa in vitro
A criopreservação é um processo em que células ou tecidos biológicos são preservados através do congelamento a temperaturas muito baixas e objetiva cessar reversivelmente, de forma controlada, todas as funções biológicas dos tecidos vivos; ou seja, manter a preservação celular de maneira que esta possa recuperar-se com alto grau de viabilidade e

5. Condrogenese a partir de celulas Mesenquimais do cordão umbilical humano estimuladas com IGF-1, TGF- beta 3, BMP-6 e BMP-2 em sistema de cultura monolayer e micromass / Chondrogenesis from Human Umbilical Cord Blood Mesenchymal Cells stimulated with TGF-beta3, IGF-1, BMP-2 and BMP-6
O sangue do cordão umbilical contem células tronco mesenquimais (CTM) indiferenciadas que tem potencial condrogênico e podem ser usadas para reparo de lesão articular. Durante o processo de condrogênese, a atuação de fatores de crescimento ainda não está totalmente elucidada. Este estudo teve como objetivo avaliar a formação de condrócitos, matri

6. Canine osteosarcoma: a study on hystopathology, immunohistochemistry and proliferative activity / Osteossarcoma canino : estudo histopatologico, imunoistoquimico e da atividade proliferativa
Osteosarcoma is the most common of all malignant canine bone tumors and has a high aggressiveness potential. From the histological point of view it is a tumor with a heterogeneous cell pattern that is characterized by the production of bone matrix and/or immature bone by osteoblasts. Systematic studies with a clear objective to evaluate histogenetic aspects

7. "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

8. Stretch-induced alternative splicing of serum response factor promotes bronchial myogenesis and is defective in lung hypoplasia
Smooth muscle (SM) develops only in organs and sites that sustain mechanical tensions. Therefore, we determined the role of stretch in mouse and human bronchial myogenesis. Sustained stretch induced expression of SM proteins in undifferentiated mesenchymal cells and accelerated the differentiation of cells undergoing myogenesis. Moreover, bronchial myogenesi

9. Liver tumors distinguished by immunofluorescence microscopy with antibodies to proteins of intermediate-sized filaments.
Antibodies against constitutive proteins of different types of intermediate-sized filaments were used in immunofluorescence microscopy on frozen sections of normal rat liver and various rat liver tumors induced by treatment with nitrosamines. Antibodies to tonofilament prekeratin stained bile duct epithelia and hepatocytes of normal liver and hepatocellular

10. Application of a Novel Method of Double APAAP Staining With Subsequent Quantitative Image Analysis to the Examination of Integrin Expression in Undifferentiated-type Gastric Carcinomas
In undifferentiated-type gastric carcinoma (UGC), recognition of cancer cells is not easy, which has hampered its precise phenotypic analysis. To examine alterations of the integrin phenotype during the progression of UGC, we used double alkaline phosphatase anti-alkaline phosphatase staining and computer-aided image analyses for the expression of α1, α2,

11. Control by the extracellular environment of differentiation pathways in 1003 embryonal carcinoma cells: study at the level of specific intermediate filaments.
1003 is a multipotential embryonal carcinoma (EC) clonal cell line which can be induced to follow different developmental pathways by altering the composition of the culture medium. When grown in serum-containing medium the great majority of 1003 cells remain undifferentiated; they express the ECMA 7 cell-surface embryonic antigen and very low amounts of vim

12. The transcription factor Sox9 has essential roles in successive steps of the chondrocyte differentiation pathway and is required for expression of Sox5 and Sox6
To examine whether the transcription factor Sox9 has an essential role during the sequential steps of chondrocyte differentiation, we have used the Cre/loxP recombination system to generate mouse embryos in which either Sox9 is missing from undifferentiated mesenchymal cells of limb buds or the Sox9 gene is inactivated after chondrogenic mesenchymal condensa
