Stem Cells Investigated to Regenerate Damaged Myocardial Tissue:
It has been investigated that damaged myocardial tissues can be regenerated by Embryonic stem cells and Adult stem cells. Embryonic stem cells are pluripotent, they can potentially give rise to the variety of cell types that are involved in regenerating damaged myocardium, including cardiomyocytes, endothelial cells, and smooth muscle cells. Human Embryonic stem cells differentiate into myocytes with the structural and functional properties of cardiomyocytes.
While undifferentiated Embryonic stem cells serve as sources of specific cell used in myocardial repair, quality control should be maintained with respect to the differentiated cells. Differentiated cells that would be used to regenerate heart tissue for transplantation must be purified before. If injected regenerative cells are accidentally contaminated with undifferentiated transplantation cells, a tumor could possibly form as a result of the cell transplant. Purification methodologies continue to improve human Embryonic stem cell differentiation. This apprehension establishes the scientific challenges that accompany the use of all human stem cells. These two things Cell proliferation and differentiation requires basic research on the molecular and genetic signals that regulate cell division and specialization. Once cells have been transplanted, objectionable interactions between the host tissue and the injected cells must be minimum. Those Cells or tissues derived from Embryonic stem cells that are available for use in humans are not tissue-matched to patients and thus would require immunosuppression to limit immune rejection.
Stem cells hold potential as a therapy to regenerate damaged myocardium. Cardiac dysfunction and the limited availability of tissue for cardiac transplantation, stem cells could eventually accomplish a significant need and recover the worth of life for millions of people. Thereby  using these cells will provide clinicians a powerful tool to repair a broken heart.

Role of Myofibroblast in normal and pathological tissue repair Tissue repair is an essential phenomenon allowing tissues and organs to recover functional properties that have been lost after an injury, either linked to a wound or to a disease. In fetal or embryonic wounds that repair without a scar or fibrosis, normal repair in the adult always leads to scar formation. In these processes of   myofibroblat   play a crucial role. When tissues are damaged, tissue homeostasis must be re-established, and repair mechanisms have to rapidly provide harmonious mechanical tissue organization, a process essentially supported by myofibroblasts. Under physiological conditions, the secretory and contractile activities of myofibroblasts are terminated when the repair is complete. Normal wound healing After injury the healing process allow immediately restoration of injured tissue. Wound healing proceeds in three interrelated stages with overlapping time Period. According to morphologica

Scaffolds for Cartilage Tissue Engineering: Tissue engineered additive manufactured scaffolds for cartilage repair , shows high prospective for growing adult cartilage tissue. Articular cartilage is the connective tissue that allows for the frictionless movement of bone within the synovial joints of the body. Its extracellular matrix consists of a combination of different types of collagen and proteoglycans that together are responsible for the viscoelastic and swelling properties of the tissue. Both natural and synthetic polymers have considered as substrate materials for the fabrication of 3D support structures. While natural source compounds, such as gelatin and alginates, are more bioactive and truly biodegradable, synthetic polymers are more predictable, reproducible, and scalable in terms of chemical and physical properties and offer a stronger structural support. Depending on the chosen scaffold fabrication technique and the end-application, both types of resour

Stem Cell-Based Therapy for Wounds Stem cells offer noteworthy prospects giving both undifferentiated and separated cells for gene therapy, drug discovery, and regenerative medicine. Wound repair is a composite process and is impacted by various factors, including cytokines, chemokines, and development factors. Hypothetically, utilization of stem cells to wounds is valuable, because it has a remarkable component of interfacing with wound condition and adjusts their movement to discharge different variables, which encourage wound recovering process. 1. Embryonic Stem Cells (ESCs) Embryonic stem cells (ESCs) are pluripotent in nature which reside within the blastocyst. These cells have a potential to differentiate into any of the three primary germ layers namely endoderm, mesoderm, or ectoderm. These cells can be differentiated into keratinocytes in presence of selected medium containing specific growth factors. These keratinocytes are capable of forming multilayered epider
