congenial cystic adenomatoid malformation of the lung (ccaml) is a rare lesion and is characterized by a multicystic mass of pulmonary tissue with an abnormal proliferation of bronchial structures. we report a case of ccaml type i presenting with heart displacement that was diagnosed prenatally.

The article deals with the physiology of endometrial regeneration after its desquamation phase during menstrual cycle in women, as well an overview studies mesenchymal/stem cells main source tissue regeneration. processes that take place first their physiological essence are repair and regeneration, contrast to proliferation, which is based on regenerative neoplasm tissues, can be observed vari...

Tissue engineering can provide a novel approach for the reconstruction of large urethral defects, which currently lacks optimal repair methods. Cell-seeded scaffolds aim to prevent stricture and scarring, as effective urothelium stromal tissue regeneration is important in repair. In this study, was evaluate effect porous ascorbic acid 2-phosphate (A2P)-releasing supercritical carbon dioxide-foa...

Abstract Morphogenesis, the process through which genes generate form, establishes tissue-scale order as a template for constructing complex shapes of body plan. The extensive growth required to build these ordered substrates is fuelled by cell proliferation, which, naively, should destroy order. Understanding how active morphogenetic mechanisms couple cellular and mechanical processes order—ra...

objective: we introduce an rgd (arg-gly-asp)-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. materials and methods: in this experimental study, the peptide was immobilized on an electrospun nanofibrous polycaprolactone/gelatin (pcl/gel) hybrid scaffold by a chemical bonding approach to improve cell adhesion properties of the scaffold. a...

An immune cell population enriched in inflamed gut tissue is shown to play a role driving CD44+ intestinal organoid proliferation, while also regulating extracellular matrix deposition and remodelling synthetic hydrogel platform.

Nanofiber scaffolds and bio-ceramic nanoparticles have been widely used in bone tissue engineering. The use of human induced pluripotent stem cells (hiPSCs) on this scaffold can be considered as a new approach in the differentiation of bone tissue. In the present study, a polyaniline-gelatin-polycaprolactone (PANi-GEL-PCL) composite nanoscaffold was made by electrospinning and modified superfic...

the purpose of this study was the utilization of different methods of tissue culture in proliferation of epithelial cells and autologous graft to cover surface areas without skin specifically, which is due to thermal burns more than 50%. in this experience we performed from rabbits and success to cover almost 24 times original donor site with autograft.
