The development of stem cells holds significant potential to transform the field of regenerative medicine by having the ability to treat and cure debilitating diseases. As such, there is an urgent need among biologists, researchers, and clinicians for a product that effectively regulates stem cell differentiation. To address this demand, the main goal of the proposed research is to develop a nanotechnology-based product (termed NanoScript). NanoScript is a tunable technology platform that effectively regulates gene expression in stem cells and differentiates stem cells into any cell lineage in a non-viral manner. NanoScript appeals to the broader stem cell market. Specifically, biologists and researchers, working at universities or private companies, who are interested in pursuing stem cell-based research are ideal customers, and are expected to be the 'early adopters.'With the advent of the proposed NanoScript technology, stem cells can safely and effectively be differentiated. By integrating small molecules onto gold nanoparticles, this team has developed NanoScript to mimic and emulate the function of natural proteins within the cell that regulate gene expression. The most attractive feature of NanoScript is its ability to regulate genes in a non-viral manner, which makes it a safe platform for fundamental and translational stem cell research. Furthermore, by making minor adjustments, NanoScript can be designed to induce the differentiation of stem cells into any cell type, thus making NanoScript a powerful and broadly-applicable platform. This interdisciplinary research and technology is the first-ever demonstration of a safe, effective, and tunable platform for stem cells.

干细胞的发展通过具有治疗和治愈衰弱性疾病的能力而具有改变再生医学领域的巨大潜力。因此，生物学家、研究人员和临床医生迫切需要一种有效调节干细胞分化的产品。为了满足这一需求，拟议研究的主要目标是开发一种基于纳米技术的产品（称为NanoScript）。NanoScript是一种可调技术平台，可有效调节干细胞中的基因表达，并以非病毒方式将干细胞分化为任何细胞谱系。 NanoScript吸引了更广泛的干细胞市场。具体来说，在大学或私营公司工作的生物学家和研究人员，谁有兴趣追求干细胞为基础的研究是理想的客户，并有望成为“早期采用者”。随着NanoScript技术的出现，干细胞可以安全有效地分化。通过将小分子整合到金纳米颗粒上，该团队开发了NanoScript来模拟和模仿细胞内调节基因表达的天然蛋白质的功能。NanoScript最吸引人的特点是它能够以非病毒的方式调节基因，这使其成为基础和转化干细胞研究的安全平台。此外，通过微小的调整，NanoScript可以被设计为诱导干细胞分化为任何细胞类型，从而使NanoScript成为一个强大且广泛适用的平台。这项跨学科的研究和技术是有史以来第一次证明了一个安全，有效和可调的干细胞平台。
