BACKGROUND Wound healing is a complex and dynamic process following damage in tissue structures. Due to extensive skin damage caused by burn injuries, this study determined the role of human adult peripheral and umbilical cord blood platelet-rich plasma on proliferation and migration in human skin fibroblasts. METHODS Platelet-rich plasma (5, 10, 15, 20 and 50% PRP) from human umbilica...
Hydrogels prepared from a bacterial fimbriae are utilized for the 2D cell culture of human dermal fibroblasts. The tunable biochemical and mechanical nature Caf1 hydrogels allow modulation morphology matrix deposition.
Dermal fibroblasts produce a collagen-rich extracellular matrix, which confers mechanical strength and resiliency to human skin. During aging, collagen production is reduced and collagen fragmentation is increased, which is initiated by matrix metalloproteinase-1 (MMP-1). This aberrant collagen homeostasis results in net collagen deficiency, which impairs the structural integrity and function o...
Background and objectives: Cancer cell resistance to common chemotherapy agents is on rise. Plants are considered valuable sources of herbal drugs for cancer therapy. The present study was conducted to investigate the in vitro antioxidant, anti-proliferative, and apoptosis-inducing properties of clove (Syzygium aromaticum L.) extract in human gastric carcinoma...
The aim of this work was to find out the effects of Annona squamosa on the formation of glycosaminoglycans and collagen during wound healing in normal and diabetic rats. Diabetes induced rats were segregated into 4 groups, each containing six animals. Groups I and III served as the normal and diabetic control while groups II and IV served as normal and diabetic treated. The animals were treated...
Human Dermal Fibroblasts Demonstrate Positive Immunostaining for Neuron- and Glia- Specific Proteins
In stem cell cultures from adult human tissue, undesirable contamination with fibroblasts is frequently present. The presence of fibroblasts obscures the actual number of stem cells and may result in extracellular matrix production after transplantation. Identification of fibroblasts is difficult because of the lack of specific fibroblast markers. In our laboratory, we isolate and expand neural...
Human diploid fibroblasts (HDF) complete a limited number of cell divisions before entering a growth arrest state that is termed replicative senescence. Two histone deacetylase inhibitors, sodium butyrate and trichostatin A, dramatically reduce the HDF proliferative life span in a manner that is dependent on one or more cell doublings in the presence of these agents. Cells arrested and subseque...
Background: The skin serves as the first line of defense for human body. Direct sunlight contains damaging radiations that can speed up ageing process skin, resulting in wrinkles, leathery dark patches, and solar elastosis. Objectives: To evaluate effect multiple irradiation related factors at protein level dermal fibroblast (HDF). overall individual irradiations such Infrared A (IRA), blue lig...
Fibroblasts play a pivotal role in the process of cutaneous wound repair, whereas their migratory ability under diabetic conditions is markedly reduced. In this study, we investigated the effect of basic fibroblast growth factor (bFGF) on human dermal fibroblast migration in a high-glucose environment. bFGF significantly increased dermal fibroblast migration by increasing the percentage of fibr...
