13. Avaliação da indiferenciação celular e indução de neurodiferenciação em co-cultivo de fibroblastos NIH 3T3 com células mononucleares do sangue de cordão umbilical
Cellular therapy represent a new frontier for the treatment of several diseases, including diseases related to central nervous system. Human umbilical cord blood is an attractive source of stem cells; however, it has a heterogeneous population with a small amount of mesenchymal stem cells. Currently, cell reprogramming induced by different methodologies can

14. Pulp tissue from primary teeth: new source of stem cells
SHED (stem cells from human exfoliated deciduous teeth) represent a population of postnatal stem cells capable of extensive proliferation and multipotential differentiation. Primary teeth may be an ideal source of postnatal stem cells to regenerate tooth structures and bone, and possibly to treat neural tissue injury or degenerative diseases. SHED are highly

15. Papel dos receptores purinérgicos P2X2 e P2X7 na diferenciação neural in vitro. / Roles of P2X2 and P2X7 purinergic receptors during in vitro neural differentiation.
Células-tronco embrionárias e células de carcinomas embrionários são modelos de diferenciação neural que permitem estudar os mecanismos de diferenciação, pois mimetizam os eventos críticos durante o início da embriogênese, adquirindo capacidade de maturação para se tornarem fisiologicamente funcionais. Esse estudo visa investigar o papel da exp

16. Rat Dlx5 is expressed in the subventricular zone and promotes neuronal differentiation
The molecular mechanisms and potential clinical applications of neural precursor cells have recently been the subject of intensive study. Dlx5, a homeobox transcription factor related to the distal-less gene in Drosophila, was shown to play an important role during forebrain development. The subventricular zone (SVZ) in the adult brain harbors the largest ab

17. Expressão do gangliosídio GD2 nas células tronco mesenquimais de tecido adiposo humano durante a diferenciação para adipócitos ou osteoblastos
As células tronco mesenquimais de tecido adiposo (MSCs-TA) são células progenitoras que residem entre adipócitos e contribuem para o turnover do tecido adiposo. Gangliosídios são glicoensfigolipídios localizados na membrana das células, envolvidos na regulação do crescimento celular, interação de superfície, sinalização transmembrana e diferen

18. Characterization and in vitro neural differentiation of human dental pulp stem cells / Caracterização e diferenciação neural in vitro de células-tronco de polpa de dente decíduo humano
A polpa do dente contém uma população de células-tronco multipotentes, que possuem a capacidade de se diferenciar em várias linhagens celulares distintas, in vitro e in vivo. Estas células possuem origem mesenquimal e, acredita-se que sejam derivadas da crista neural. Elas podem ser induzidas a se diferenciar em células de osso, cartilagem, músculo l

19. Expression of D-type cyclins in differentiating cells of the mouse spinal cord
The D-type cyclins form complexes with the cyclin dependent (CD) kinases CDK4 and CDK6 and promote the G1-S phase transition of the cell cycle by antagonizing the retinoblastoma suppresser protein pRB. In the developing nervous system D-type cyclins show spatially and temporally dynamic patterns of expression. We demonstrated that cyclin D1 was transiently e

20. Analysis of P2X2 e P2X4 receptors during neuronal differentiation / Análise dos receptores P2X2 e P2X4 durante a diferenciação neuronal
During the development of the nervous system, oscillations of intracellular calcium concentrations activate programs of gene expression resulting in proliferation, migration and neuronal differentiation of embryonic cells. In this thesis, the participation of ionotropic P2X2 and P2X4 receptor subtypes, whose receptor channels are highly permeable for calcium

21. Placas maxilo-dentárias em Rincossauros Hyperodapedon Huxley, 1859. Histologia e morfogênese maxilo-dental: nova abordagem.
O estudo das estruturas da placas maxilo-dentárias dos rincossauros Hyperodapedon Huxley, 1859, do Triássico da Formação Santa Maria, em nova abordagem histológica e ontogênica resultou na identificação da natureza do esmalte aprismático verdadeiro, de variados elementos histológicos dentinários e osteológicos, e de um centro de ossificação per

22. Dexamethasone blocks the migration of the human neuroblastoma cell line SK-N-SH
Glucocorticoids (Gc) influence the differentiation of neural crest-derived cells such as those composing sympathoadrenal tumors like pheochromocytomas, as well as neuroblastomas and gangliomas. In order to obtain further information on the effects of Gc on cells evolving from the neural crest, we have used the human neuroblastoma cell line SK-N-SH to analyze

23. Clinical and pathological prognostic factors after resection for pancreatic cancer / "Estudo dos fatores clínico-patológicos no prognóstico de pacientes submetidos à ressecção de adenocarcinoma pancreático"
The aim of the present study is to correlate clinical and pathological finding with survival in patients with pancreatic adenocarcinoma treated with surgical resection. Fifty six patients ressected were studied retrospectively. There were 32 females (57,1%) and 24 males (42,8%) with mean age of 58,1 years. Pylorus preserving duodenopancreatectomy were perfor

The aim of this study was to verify the HOXB13 and HHEX genes expression in oral squamous cell carcinoma (OSCC) using Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) and in situ Hybridization techniques. Tumoral tissues and adjacent non-tumoral oral mucosa specimens were obtained from 30 patients with OSCC at the Head and Neck Surgery Service HC (FM
