    Dendrobium hybrid orchid is popular in orchid commercial industry due to its short life cycle and ability to produce various types of flower colours. This study was conducted to identify the morphological, biochemical and scanning electron microscopy (SEM) analysis in the Dendrobium sonia-28 orchid plants. In this study, 0.05 and 0.075 % of colchicine-treated Dendrobium sonia-28 (4-week-old culture) protocorm-like bodies (PLBs) were treated in different concentrations of melatonin (MEL) posttreatments (0, 0.05, 0.1, 0.5, 1, 5 and 10 μM). Morphological parameters such as number of shoots, growth index and number of PLBs were determined. In the 0.05 and 0.075 % of colchicine-treated PLBs which were posttreated with 0.05 μM MEL resulted in the highest value of the morphological parameters tested based on the number of shoots (84.5 and 96.67), growth index (16.94 and 12.15) and number of PLBs (126.5 and 162.33), respectively. SEM analysis of the 0.05 μM MEL posttreatment on both the colchicine-treated regenerated PLBs showed irregular cell lineages, and some damages occurred on the stomata. This condition might be due to the effect of plasmolyzing occurred in the cell causing irregular cell lineages.

    The therapeutic potential of human mesenchymal stromal stem cells (hMSCs) for cell-based therapeutic is greatly influenced by the in vitro culture condition including the culture conditions. Nevertheless, there are many technical challenges needed to be overcome prior to the clinical use including the quantity, quality, and heterogeneity of the cells. Therefore, it is necessary to develop a stem cell culture procedure or protocol for cell expansion in order to generate reproducible and high-quality cells in accordance with good manufacturing practice for clinical and therapeutic purposes. Here we assessed the MSCs characteristic of human Wharton's jelly mesenchymal stromal cells in in vitro culture according to the criteria established by the International Society for Cellular Therapy. Besides, the viability of the WJMSCs was determined in order to increase the confidence that the cells are employed to meet the therapeutic efficacy.
