Micro- and Nanoengineering Approaches to Control Stem

Micro- and Nanoengineering Approaches to Control Stem Cell-Biomaterial Interactions

As our population ages, there is a greater need for a suitable supply of engineered tissues to address a range of debilitating ailments. Stem cell based therapies are envisioned to meet this emerging need. Despite significant progress in controlling stem cell differentiation, it is still difficult to engineer human tissue constructs for transplantation. Recent advances in micro- and nanofabrica...

Microengineered synthetic cellular microenvironment for stem cells.

Stem cells possess the ability of self-renewal and differentiation into specific cell types. Therefore, stem cells have great potentials in fundamental biology studies and clinical applications. The most urgent desire for stem cell research is to generate appropriate artificial stem cell culture system, which can mimic the dynamic complexity and precise regulation of the in vivo biochemical and...

Geometry–Force Control of Stem Cell Fate

Tissue engineering requires tight control of stem cell function. Among many physical signals such as stretch and perfusion, geometrical cues have received much attention and have widely been recognized as an important factor in scaffold design. Here we review a variety of approaches that control stem cell fate at different levels of strictness, including micro-contact printing, microwells, dire...

Comparison in Chemical Compositions of the Essential Oil from Leaves of Lippia citriodora H.B.K. Plantlets Produced from Micro-propagation and Stem Cutting

Background: Lemon verbena (Lippia citriodora H.B.K.) is an aromatic and medicinal plant of family Verbenaceae, which cultivated in the North region of Iran. Objective: This comparative study was carried out on essential oil content and composition of Lippia citriodora H.B.K. from micro-propagated and rooted apical stem cutting plantlets. Methods: The micro-propagated plantlets were obtained ...
