1. Human Embryonic Stem Cell-Derived Mesenchymal Progenitor (hESCs-MP) Growth on Nanostructured Ti6Al4V Surfaces
Nanotexturing processes that focus on enhancing the bone-implant contact, such as electropolishing, have been proposed. The aim of this work was to evaluate the influence of Ti6Al4V surface morphology on human embryonic stem cell-derived mesenchymal progenitor (hESCs-MP) growth. Three surface treatments were used in this study: mechanically polished samples

2. Combination of heterologous fibrin sealant and bioengineered human embryonic stem cells to improve regeneration following autogenous sciatic nerve grafting repair
Abstract Background Peripheral nerve injury is a worldwide clinical problem, and the preferred surgical method for treating it is the end-to-end neurorrhaphy. When it is not possible due to a large nerve gap, autologous nerve grafting is used. However, these surgical techniques result in nerve regeneration at highly variable degrees. It is thus very importa

3. Fetal Cerebrospinal Fluid Promotes Proliferation and Neural Differentiation of Stromal Mesenchymal Stem Cells Derived from Bone Marrow
ABSTRACT Embryonic cerebrospinal fluid (E-CSF) contains many neurotrophic and growth factors, acts as a growth medium for cortical progenitors, and can modulate proliferation and differentiation of neural stem cells. Mesenchymal stem cells (MSCs) are multipotential stem cells that can differentiate into several types of mesenchymal cells as well as nonmesenc

4. Cultivation and Biological Characterization of Chicken Primordial Germ Cells
The purpose of this work was to investigate the isolation, culture process of chicken gonadal primordial germ cells (PGCs) and study their biological characterization. PGCs were harvested from 5.5-day-old chicken embryonic genital ridges and explanted onto chicken embryonic fibroblasts (CEFs). The results showed that the primary cultivation of chicken PGCs o

5. Evo-devo of non-bilaterian animals
The non-bilaterian animals comprise organisms in the phyla Porifera, Cnidaria, Ctenophora and Placozoa. These early-diverging phyla are pivotal to understanding the evolution of bilaterian animals. After the exponential increase in research in evolutionary development (evo-devo) in the last two decades, these organisms are again in the spotlight of evolution

6. Development of the endocrine pancreas and novel strategies for β-cell mass restoration and diabetes therapy
Diabetes mellitus represents a serious public health problem owing to its global prevalence in the last decade. The causes of this metabolic disease include dysfunction and/or insufficient number of β cells. Existing diabetes mellitus treatments do not reverse or control the disease. Therefore, β-cell mass restoration might be a promising treatment. Severa

7. From abortion to embryonic stem cell research: Biossociality and the constitution of subjects in the debate over human rights
O artigo analisa a presença do discurso dos direitos humanos nos debates sobre o aborto e sobre a pesquisa com células-tronco embrionárias como integrante do processo de biossocialidade. Tais questões emergem no campo da saúde reprodutiva e chegam à esfera do Direito em vista de problemas éticos. O discurso para constituir fetos e embriões em sujeito

8. The ability of mouse nuclear transfer embryonic stem cells to differentiate into primordial germ cells
Nuclear transfer embryonic stem cells (ntESCs) show stem cell characteristics such as pluripotency but cause no immunological disorders. Although ntESCs are able to differentiate into somatic cells, the ability of ntESCs to differentiate into primordial germ cells (PGCs) has not been examined. In this work, we examined the capacity of mouse ntESCs to differe

9. Functional properties of a Brazilian derived mouse embryonic stem cell line
As linhagens de células tronco pluripotente embrionárias de camundongos (mESC) são derivadas da massa celular interna de blastocistos da fase inicial dos embriões. Como diferentes trabalhos têm demonstrado que a modulação dos canais iônicos pode interferir tanto no crescimento como no processo de diferenciação das células tronco embrionárias, tan

10. 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

11. VP22 herpes simplex virus protein can transduce proteins into stem cells
The type I herpes simplex virus VP22 tegument protein is abundant and well known for its ability to translocate proteins from one cell to the other. In spite of some reports questioning its ability to translocate proteins by attributing the results observed to fixation artifacts or simple attachment to the cell membrane, VP22 has been used to deliver several

12. Início e manutenção da inativação do cromossomo X em células humanas / Establishment and maintenance of X-chromosome inactivation in human cells
Em fêmeas de mamíferos, um dos cromossomos X é inativado proporcionando compensação de dose entre os produtos gênicos de machos e fêmeas. A inativação do cromossomo X (ICX) ocorre no embrião em desenvolvimento, e se caracteriza pela aquisição de marcas heterocromáticas no cromossomo X inativado (Xi), que são mantidas nas células somáticas ao
