“…This study clearly showed that the application of Bambusa tulda decreased mesenchymal stem cells. In previous reports, mesenchyamal stromal cells are treated with individual and mixtures of crude herbal extracts, as well as with purified compounds from herbal extracts, to investigate the mechanisms and effects of differentiation of stem cells [5,[12][13][14][15]. Er-Xian Decoction, a traditional Chinese herbal formula widely used for postmenopausal osteoporosis treatment is reported to stimulate osteoblastic differentiation of bone mesenchymal stem cells in ovariectomized mice by rescuing several gene expressions that were dysregulated including osteocalcin [12].…”

“…In this report, the decreased osteogenic differentiation of mesenchymal stem cells derived from gingival has been applied irrespective of different concentration of BBT. Previously, differentiation effects of individual herbal extracts have been tested on human mesenchymal stem cells mainly derived from bone marrow and elaborated on the plausible underlying mechanisms of action [5]. Mesenchymal stem cells may be isolated from various tissues including gingival, as used in this study [16][17][18][19][20].…”

“…Many plants are shown to possess antimicrobiological and anti-inflammatory functions and they have been applied for the the treatment of flatulence, jaundice, menstrual difficulties, hematuria, hemorrhage, and colic [4]. More recently, potential role of herbal medicine on stem cell have been tested in vitro and in vivo experiments [5]. One of the traditional Chinese herbal medicine, Sarcandra glabra is reported to protect mesenchymal stem cells from oxidative stress [6].…”

Bambusa tulda has been used for various Purpose and is considerd as one of the most useful bamboo species. This study aimed to evaluate the effects of Bambusa tulda extract (BBT) on the osteogenic differentiation and mineralization of human mesenchymal stem cells. Stem cells obtained from gingivae were cultured in an osteogenic medium in the presence of BBT at concentrations ranging from 0.001% to 1%. Evaluations of cell morphology and cellular viability were done at days 1, 3, 5 and 7. Alkaline phosphatase activity assays and Alizarin red S staining were performed to evaluate the osteogenic differentiation of stem cells. The morphology of stem cells in the presence of BBT at final concentrations of 0%, 0.001%, 0.01%, 0.1%, and 1% did not show any noticeable changes when compared with the untreated control group. The treatment of BBT (from 0.001% to 1% groups) showed decrease in alkaline phosphatase activity. The results of the Alizarin Red S staining showed a significant decrease with application of BBT. Conclusively, Bambusa tulda had influenced the osteogenic differentiation of the stem cells derived from the gingiva. Thus, the use of Bambusa tulda may produce adverse effects onto oral tissues. The concentration and application time of Bambusa tulda should be meticulously controlled to minimize the adverse effects.

“…The related approaches were used by one of the same researchers from the aforementioned to form a BC pellicle with MgO nanoparticles, but this MgO composite with BC was found to have much higher bactericidal effects that for the case with the CuO nanoparticles [134]. Cellulose composites with silver nanoparticles have also been examined for their antibacterial effects and have shown that silver nanoparticles less than 20nm in diameter showed better zones of inhibition than composites with silver nanoparticles greater than 20nm in diameter [135]. Bacterial cellulose has also been impregnated with ZnO nanoparticles (grown to 70-100nm in diameter) by immersing the BC pellicle in zinc nitrate solution followed by a NaOH solution [136].…”

Increasing interest in bacterial cellulose due to the huge potential which exists for the development of this new biomaterial for medical applications has been met with recent growth in research in engineering this unique microbial manufactured material. The mechanical properties, porosity, and biocompatibility of bacterial cellulose derived biomaterials are particularly attractive for use in wound healing, tissue engineering, and drug delivery applications. Advances in synthetic biology and soft materials engineering are pushing the value of this biomaterial to new levels. This review provides and in-depth discussion of these most recent approaches in processing as well as physical, chemical, and genetic modification of bacterial cellulose toward further improvement and expansion of its functionality. In addition, we provide specific attention to the marketed applications of the resulting engineered materials for medical research and conclude with prospective areas of consideration for expanding the clinical utility of this biomaterial to new directions.

“…CNCs have been widely applied as nanofillers for composites, templates for functional materials, and raw materials for barrier films, due to their outstanding properties such as renewability, low cost, biodegradability, low toxicity, optical transparency, low thermal expansion, high aspect ratio, and high mechanical modulus . Considering their importance in material science, CNCs produced from various sources, such as coconuts, cotton, wood pulp, bamboo, sugarcane bagasse, rice husk, soy hulls, bacteria, and tunicate, have been reported, and their morphology as well as properties have also been comprehensively investigated. Usually, cellulose nanofibrils can be extracted from natural sources by mechanical and oxidation processes, while rod‐like CNCs can be obtained by acid hydrolysis method …”

Cellulose nanocrystals (CNCs) as attractive nanomaterials are widely distributed in higher plants, algae, and marine animals. Herein, three kinds of CNCs were isolated by sulfuric acid hydrolysis from cotton pulp, algae, and tunicate cotton, respectively. Their morphologies and size were characterized by scanning electron microscope and atomic force microscope. The results showed that the aspect ratio of CNCs was in the order of CNCs from cotton pulp (CCNCs) (15 ± 10) < CNCs (ACNCs) from algae (ACNCs) (18 ± 12) < CNCs from tunicate (TCNCs) (75 ± 60). The phase transitions of CNC suspensions were also determined by phase diagram and rheological experiments. Two critical concentrations from isotropic to biphasic phase (Ci) and from biphasic to anisotropic phase (Ca) were measured and calculated, indicating that CNCs with higher aspect ratio reached Ci and Ca at lower concentration. Furthermore, the critical concentrations were also checked by polarized optical microscopy measurement. This work provided important information for construction of CNCs reinforced nanocomposites and investigation of CNCs chiral nematic liquid crystals. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
