“…In this investigation, we report the use of cells derived from the human cumulus (hCC), the in vivo physical support, and microenvironment of the developing oocyte, as feeder to maintain the undifferentiated form of hiPS cells. The rationale for using hCC as feeder is that, during in vitro fertilization procedure, the coculture of human embryos with autologous cumulus improves embryo quality, blastocyst formation and pregnancy rate [36,37]. In this study, we show that during their propagation on hCC feeder, the hiPS cells maintain the expression of the typical pluripotency markers and the ability to differentiate in vitro into many cell types, including those with contracting myocardial tissue.…”

Pluripotency is at the crossroads of stem cell research and biology of reproduction. The mature metaphase II oocyte contains the key factors for pluripotency induction and maintenance as assessed by its capacity to reprogram somatic nuclei. The cumulus cells (CCs) niche that surrounds the oocyte is crucial for its maturation and presumably for the oocyte to acquire its competence to confer pluripotency. In this study, we examined whether cells cultured from the human mature metaphase II oocyte CC niche (hCC) could be used as feeders for the propagation of human induced pluripotent stem cells. The induced pluripotent (iPS) cells cultured on hCC (hCC-iPS) were assessed for their pluripotency potential by their expression of pluripotency-associated genes such as Oct4, Nanog, and TRA1-60 and their competence to differentiate into the three germ layers in vitro (embryoid bodies) as well as in vivo (teratoma formation). We show that not only the hCC-iPS cells maintained their pluripotency potential, but they also exhibited much better self-renewal performance in terms of proliferation rate compared to the same cells cultured on human foreskin fibroblast (hFF) feeders (hFF-iPS). A comparative gene expression profile study of hCC and hFF revealed significant differences (P < 0.05) in expression of cellular matrix components and an upregulation in hCC of genes known to be important players in cell proliferation such as interleukin 6 gene (IL6).

“…Taipei invested one billion New Taiwan Dollars (approximately 33.33 million US Dollars) and partnered with semi-government and private ICT corporations to build its city-wide broadband and Wi-Fi network. To promote greater usage of the network, the Ma administration launched a series of digital education and governmental initiatives, such as providing online life-long education and digital literacy training, setting up websites and databases for all government agencies, creating a digitally verifiable personal identity infrastructure for online banking and promoting a contactless smartcard payment system (EasyCard) for Taipei’s metropolitan public transportation services (Alamsyah et al, 2016; Tan and Tan, 2009).…”

Provincialising smart urbanism in Taipei: The smart city as a strategy for urban regime transition

2020

View full text Add to dashboard Cite

The appeal of revolutionising urban governance through information technologies has prompted cities across the globe to pursue smart city initiatives. The mainstream scholarship on these initiatives has mostly focused on technology and corporate-led urban development, and it also often privileges the experience of cities in the global North. Nevertheless, this mainstream understanding of the smart city may obscure emerging new power dynamics and locally contextualised processes associated with smart urban development, especially in cities at the global periphery. Inspired by post-colonial theories, this article makes the case for ‘provincialising’ smart urbanism by dislodging technology from the centre of analysis, accentuating perspectives of cities outside the locations where the smart city knowledge is traditionally produced and attending to power relationships. In our case study of Taipei, this provincialising approach helps unveil various logics, intentionalities, assemblages and power dynamics through which the smart city is employed as a political strategy to facilitate urban regime transition. We argue that the current non-affiliated Ko administration exploits the veneer of technological superiority and political neutrality of its smart city agenda to set a new growth agenda, form new development coalitions, establish new institutions and incorporate rising populist momentum into policy-making. Focusing on the politics of being smart, our findings illustrate how smart city experiments reshape power dynamics and regime formation through reorganising actors and interest groups, reconfiguring government institutions, reallocating resource distribution and, in the end, bolstering governing legitimacy.
