Extracellular matrix (ECM) is an extensive molecule network composed of three major components: protein, glycosaminoglycan, and glycoconjugate. ECM components, as well as cell adhesion receptors, interact with each other forming a complex network into which cells reside in all tissues and organs. Cell surface receptors transduce signals into cells from ECM, which regulate diverse cellular functions, such as survival, growth, proliferation, migration, differentiation, and some vital role in maintaining cells homeostasis. This chapter emphasizes the complex of ECM structure to provide a better understanding of its dynamic structural and functional characterization and multipotency. In this chapter the implications of ECM in tissue remodeling are mainly discuss on the neuronal regeneration and wound healing mechanism in the presence of human umbilical mesenchymal conditioned medium (HU-MSCM).

This research was conducted to clarify the capability of human umbilical mesenchymal stem cells conditioned medium (HU-MSCM) to promote regenerations of primary wound healing on the incision skin injury. In this study, two approaches in vitro and in vivo already done. On in vitro analysis, tube formation was performed using HU vein endothelial cells in the presence of HU-MSCM, in some experiments cells line was incubated prior the presence of lipopolysaccharide and HU-MSCM then apoptosis assay was performed. Furthermore, in vivo experiments 12 female rats (Rattus norvegicus) were used after rats anesthetized, 7 mm wound was made by incision on the left side of the body. The wound was treated with HU-MSCM containing cream, povidone iodine was run as a control. Wound healing regenerations on the skin samples were visualized by hematoxylin-eosin staining. In vitro models elucidate HU-MSCM may decreasing inflammation at the beginning of wound healing, promote cell migration and angiogenesis. In addition in vivo models show that the incision length on the skin is decreasing and more smaller, HE staining describe decreasing of inflammation phase, increasing of angiogenesis, accelerate fibroplasia, and maturation phase. Taken together our observation indicates that HU-MSCM could promote the acceleration of skin tissue regenerations in primary wound healing process.

Holy basil (Ocimum sanctum Linn) or known also as “kemangi” in Indonesia is a plant commonly used as a herb in Asian countries. It is also medicinal with antipyretic, anti-inflammatory, anti-cancer, and neuroprotective properties. This dataset article provides broad screening of the phytochemical component of Ocimum sanctum ethanolic extract (EEOS) as well as a secondary metabolite profile of EEOS. Analyses were done qualitatively and quantitatively using a combination of spectrophotometer, thin layer chromatography, Fourier transform infrared spectroscopy (FTIR), and ¹H-nuclear magnetic resonance (¹H-NMR). Results showed that Ocimum sanctum ethanolic extract contains phytochemical compounds, including flavonoids, phenols, tannins, saponins, alkaloids, steroids, and terpenoids. In addition, a secondary metabolite was found and classified into metabolite groups including alcohol, amine, carboxylic acid, alkane, alkene, aldehyde, phenol, ether, sulfur, halogen, benzene, nitrogen, sterol, amino acid, carbohydrate, and nitrogen.

Ocimum sanctum (OS) is tropical herbal plant which is easy to find and widely used as a vegetable food in Indonesia. In last decade, lung adenocarcinoma was in top position as male cancer disease in Indonesia. Recently, emerging data showing the extracts of different species of Ocimum exhibiting the anti-tumor properties. Further studies on lung lewis carcinoma demonstrated pro-apoptosis effects after the treatment with Ocimum extracts. However, the effect of OS of Indonesian origin in human alveolar pulmonary adenocarcinoma A549 cells remain unclear. Therefore, we aimed to investigate effects of ethanolic extract OS (EEOS) in A549 cell culture systems. Cell adhesion and viability assays revealed that EEOS significantly decreased the attachment into extracellular matrix of A549 cells. Morphological examination AO/EB and DAPI staining indicated that EEOS induced the cells shrinkage, DNA fragmentation and condensation of A549 cells. Further, EEOS treatment induced the apoptosis rate followed by up-regulation of reactive oxygen species (ROS), caspase-3 expression and decreased anti-apoptotic protein Bcl-2. This condition also suppressed the expression of SOD2 as well as the GPx. In conclusion, our findings indicate that EEOS suppressed the viability of A549 cells, which may result from the activation of ROS promoting the apoptosis signaling via mitochondrial intrinsic pathway. Taken together, EEOS might be a good therapeutic potential to further understand its properties in the treatment of lung carcinoma.

This research was conducted to identify the expression of choline acetyltransferase (ChAT) in human cerebral microvascular endothelial cells (HCMECs) and to clarify the capability of Ocimum sanctum Linn. ethanolic extract to stimulate the presence of ChAT in the aging HCMECs. In this study, we perform an in vitro analysis some in the presence of an ethanolic extract of O. sanctum Linn. as a stimulator for the ChAT expression. HCMECs are divided become two groups, the first is in low passage cells as a model of young aged and the second is in a high passage as a model of aging. Furthermore to analysis the expression of ChAT without and with extract treatments, immunocytochemistry and flow cytometry analysis were performed. In addition, ChAT sandwich enzyme-linked immunosorbent assay is developed to detect the increasing activity of the ChAT under normal, and aging HCMECs on the condition treated and untreated cells. In our in vitro models using HCMECs, we found that ChAT is expressed throughout intracytoplasmic areas. On the status of aging, the ethanolic extract from O. sanctum Linn. is capable to stimulate and restore the expression of ChAT. The increasing of ChAT expression is in line with the increasing activity of this enzyme on the aging treated HCMECs. Our observation indicates that HCMECs is one of the noncholinergic cells which is produced ChAT. The administrated of O. sanctum Linn. ethanolic extract may stimulate and restore the expression of ChAT on the deteriorating cells of HCMECs, thus its may give nerve protection and help the production of acetylcholine.
