Protocol for Testing Human Melanoma Exosomes that Shift the Healthy Phenotype of Human Dermal Cells.

Exosomes are small membrane-derived vesicles that transmit DNA constituents, mRNAs, microRNAs, and proteins from donor cells to a receiver cell. Various cells comprising of mesenchymal, immune, and cancer cells discharge exosomes. Cancer cell exosomes form the entry and reprogramming of essentials connected to a tumor environment.

ΔNp63 Regulates Homeostasis, Stemness, and Suppression of Inflammation in the Adult Epidermis.

The p63 transcription factor is critical for epidermis formation in embryonic development, but its role in the adult epidermis is poorly understood. In this study, we show that acute genetic ablation of ΔNp63, the main p63 isoform, in adult epidermis disrupts keratinocyte proliferation and self-maintenance and, unexpectedly, triggers an inflammatory psoriasis-like condition. Mechanistically, single-cell RNA sequencing revealed the downregulation of cell cycle genes, upregulation of differentiation markers, and induction of several proinflammatory pathways in ΔNp63-ablated keratinocytes.

A Comprehensive Review: Molecular and Genetic Background of Indirect Inguinal Hernias.

Background: The occurrence of indirect inguinal hernias (IIH) is 5 times more prevalent than that of direct inguinal hernias (IH) and it is 7 times more common in males, owing to the attendance of the processus vaginalis (PV) throughout testicular descent.

Summary: In children, the immense mainstream of IH is indirect. The progress of IIH development in children is instigated with a patent PV, which is mostly treated by simple herniorrhaphy.

Modeling Schizophrenia with Glioblastoma Cells: In Vitro Analysis of Risperidone Treatment on Glial Spheroids.

Objective: Glioblastoma is the most malicious type of glioma presenting a genetic background via diverse mutations and exhibits differential sensitivity to treatment. Meanwhile, schizophrenia is a heterogeneous disease with a complex etiology. Studies report an elevation in pro-inflammatory cytokines in patients with schizophrenia and changes in biochemical metabolism.

Deficiency of epithelial-mesenchymal transition causes child indirect inguinal hernia.

Introduction: Epithelial-mesenchymal transition (EMT) describes rapid changes in cellular phenotype. During EMT, epithelial cells down-modulate cell-cell adhesion, alter polarity, reorganize cytoskeleton, become isolated, motile, and resistant to anoikis. Epithelial breakdown and epithelial cell migration are the key processes involved in the obliteration of processus vaginalis.

Decellularization Concept in Regenerative Medicine.

Decellularized organs and tissues are effectively utilized in a diversity of regenerative medicine purposes, and the decellularization approaches employed differ as broadly as the tissues/organs of concern. Biological scaffold substances formed by extracellular matrix (ECM) are mostly produced with methods that include decellularization of tissues. Conservation of the multifaceted arrangement and three-dimensional (3D) construction of the ECM is very wanted but it is documented that almost every approach of decellularization cause disturbance of the organization and possible forfeiture of surface organization and conformation.

In vitro artificial skin engineering by decellularized placental scaffold for secondary skin problems of meningomyelocele.

Background: Meningomyelocele (MMC) is a condition that is originated by the fusion defect of the neural tube. It is a congenital anomaly and can be characterized by spinal cord defects and impaired skin integrity. It is very important to close the skin openings via three-dimensional artificial skin like construction for preventing infection and maintaining the healthy skin structure.

Characterization and Differentiation of Stem Cells Isolated from Human Newborn Foreskin Tissue.

Circumcision is described as a cultural, medical, and religious process which states surgical removal of the foreskin either partly or fully. Cells isolated from the circumcised tissues are referred as foreskin cells. They have been thought as feeder cell lines for embryonic stem cells.
