Microgels Enable iPSCs to Assemble, Expand, and Differentiate Into Organoids—From Sizable to High‐Throughput

open access: yesAdvanced Materials, EarlyView.
A chemically defined PEG‐based microgel platform enables scalable, reproducible production of three‐dimensional microgel‐iPSC constructs in multiple sizes. The system is compatible with high‐throughput automation and supports human iPSC expansion and differentiation within a single construct, including directed differentiation into cardiac organoids ...

Soft and Transient Bioelectronics Enabled by Polymer‐Free Ti3C2Tx MXene Hydrogels

open access: yesAdvanced Materials, EarlyView.
We present Ti3C2Tx MXene hydrogel (MXgel) bioelectronics, a soft, flexible, and fully transient platform for high‐fidelity neural recording and stimulation. MXgel bioelectronics exhibit exceptional electrical conductivities, low electrochemical impedances, and high charge injection capacities.

Fabrication of Aligned Polycaprolactone Nanofibrillar Bundles to Control Cell‐Mediated Collagen Deposition in Engineered Cartilage

open access: yesAdvanced Materials, EarlyView.
Melt electrofibrillation (MEF) enables the fabrication of nanofibrillar PCL scaffolds with defined architectures that guide cellular alignment and retention during cartilage tissue engineering. Unlike conventional melt electrowriting, MEF consistently directs collagen type II‐rich extracellular matrix organization, providing a tunable platform to ...

The role of seed coats in seed viability

The Botanical Review, 1994
The seed coat is the seed’s primary defense against adverse environmental conditions. A hard seed coat protects the seed not only from mechanical stress but also from microorganism invasion and from temperature and humidity fluctuations during storage.

Determination of ten stilbenes and their antioxidant activity of peony seed coat, seed kernel and seed coat extracts

China Journal of Chinese Materia Medica, 2016
The seed of tree peony and herbaceous peony contained a variety of stilbenes which possess many pharmacological activities, such as antitumor, anti-inflammatory, allergy and neuraminidase inhibition. In order to develop and use peony seed resources, a simple and sensitive HPLC-DAD was developed for simultaneous determination of 10 stilbenes in peony ...

Mucilaginous Seed Coats

Weed Science, 1973
Mucilage was detectable on the seeds of 8% of 233 plant species collected in Nevada and adjacent California. Mucilaginous species were restricted to the Cruciferae, Euphorbiaceae, Labiatae, Onograceae, and Plantaginaceae. Many of the species with mucilaginous seed coats are weeds.

Peroxides in seed coatings

Outlook on Agriculture, 1984
Most seeds require the presence of oxygen during the early stages of germination and even in rice, where it is not essential, oxygen favours a good start. Recent research has explored the practical advantages of coating seeds with peroxide-containing dressings which will liberate oxygen at a controlled rate.

Dormancy in seeds imposed by the seed coat

1965
The resting condition of many seeds, especially those of different farm and garden crops, is maintained only as long as the seeds are in dry storage. As soon as a suitably moist medium and a favorable temperature are provided germination proceeds almost immediately.

Effect of seed coat on peach seed germination

Scientia Horticulturae, 1985
Abstract Various treatments to remove the seed coat surgically revealed its role in preventing germination of non-stratified peach seed. The peach embryo from a non-chilled seed is not dormant, as it germinates readily when the seed coat is completely removed.

Effects of tallowtree seed coat on seed germination

Journal of Forestry Research, 2011
We measured physiological parameters including water uptake, in-vitro embryo germination ratio, and seed coat structure observed by scanning electron microscopy (SEM) to explore the influence of seed coat on the germination of seeds of tallow tree (Sapium sebiferum (Linn) Roxb.). Tallow tree seeds had good water permeability.
