Gel constructs containing fibers induced greater axon outgrowth distances with significantly more directionality along the aligned fibers. Interestingly, wet-spun type I collagen from rat tail tendon displayed a highly aligned outgrowth pattern from DRG axons suggesting potential use for peripheral nerve repair.

    A significant gap exists in early-stage seed capital for technology-based new ventures. This article reports the results of a survey of embryonic firms in the southwestern United States, which received significant amounts of their initial capital from strategic partners. High levels of satisfaction with the alliance were reported by the capital recipients and the alliances tended to evolve into long-term relationships. The alliances were set up to gain access to risk capital as well as complementary tangible and intangible assets such as embodied technologies, patents, know-how, and distribution networks.

  • Fault-tolerance properties and self-healing abilities implementation in FPGA-based embryonic hardware systems

    The cell-based structure, which makes up the majority of biological organisms offers the ability to grow with fault-tolerance abilities and self-repair. By adapting these mechanisms and capabilities from nature, scientific approaches have helped researches understand related phenomena and associated with principles to engine complex novel digital systems and improve their capability. Founded by these observations, the paper is focused on computer- aided modeling, simulation and experimental research of embryonic systems fault-tolerance and self-healing abilities, with the purpose to implement VLSI hardware structures which are able to imitate cells or artificial organism operation mode, with similar robustness properties like their biological equivalents from nature. The presented theoretical and simulation approaches were tested on a laboratory prototype embryonic system (embryonic machine), built with major purpose to implement self-healing properties of living organisms.

  • Embryonic machines that grow, self-replicate and self-repair

    After a reminder about embryonic machines endowed with universal construction and universal computation properties, this paper presents a novel architecture providing additional self-repairing capabilities. Based on the hardware implementation of the so-called Tom Thumb algorithm, the design of this machine leads to a new kind of cellular automaton made of a processing unit and a control unit. The corresponding hardware implementation results from a new and straightforward methodology for the design of self-replicating and self-repairing computing machines of any dimensions.

  • Effect of EMP on mice polydactylia and related genes expression (Gli3, Shh and Fgf4) during the development of mice limbs

    This paper observe mice polydactylia induced by EMP and related genes expressions (GliS5 Shh and Fgf4) during the development of mice limbs. Mature female mice were mated overnight with male mice (2:1). The morning on which a vaginal plug was found was designated as fetation-day-0. The pregnant mice were randomly divided into control group and EMP radiation group. Mice in the EMP radiation group were exposed to EMP from fetation-day-7 to fetation- day-10. The field intensity was 400 kVmiddotm-1 with 400 pulses. On the fetation-day-18, the embryos were taken out by cesarean section. The polydactylia were recorded. Morphological analysis of polydactylia was performed by using Alcian blue-Alizarin red staining method. The pregnant mice were randomly divided into negative control group, positive control group and EMP radiation group. Mice in the EMP radiation group were exposed to EMP from fetation-day-7 to fetation-day-10. The field intensity was 400 kVmiddotm-1 with 400 pulses. Mice in the positive control group were injected with 300 mgmiddotkg-1 of BrdU on the fetation-day-9 and fetation-day-10 days. On fetation-day-11, the embryos were taken out by cesarean section. The expressions of Gli3 Shh and Fgf4 were detected by Whole-mount in situ hybridization. This subject was supported by National Natural Science Fund (No. 60471032). Morphological analysis indicated that the polydactylia rate of the EMP radiation group was significantly higher than that of the control group (P<0.05). And it was also indicated that limb abnormality often occurred to the hindlimbs. In embryo limbs (fetation-day-11) of the EMP radiation group and the positive control group, the ectopic expression of Fgf4 was detected in AER; the overexpression and ectopic expression of Shh were detected in the ZPA; the decreased expression of Gli3 was detected in mesenchyme cells. The occurrence of polydactylia in mice increased after EMP radiation and it may have some relationship with the abnormal expressions of the above-mentioned genes

  • Microfluidic switch for embryo and cell sorting

    We present measurements and simulation of fluid flow and sphere motion in a pressure-driven microfluidic sorter designed for Drosophila embryos. We simulated the flow fields for different channel layouts and flow parameters to find geometries and conditions for optimised embryo movement. The microfluidic switch has a designed switching time of 360 /spl mu/s. We validated the sorter design with fluid experiments in devices fabricated from silicon and Pyrex wafers. The experimental and simulated results are compared both qualitatively and quantitatively by examining the concentration distribution of fluids. This type of microfluidic sorter is promising for micromanipulation of a variety of biological cells, and provides automated operations for higher throughput and accuracy.

  • Automated segmentation and alignment of mitotic nuclei for kymograph visualisation

    The mechanics of many biological processes can only be uncovered through the analysis of spatio-temporal data. Kymographs are a popular tool for visualising dynamic processes whose movements can be mapped into a single dimension, such as mitosis, or cell division. However, global movements of a cell means the region of interest (ROI) used to create the kymograph must move with each frame. Here we present an automated algorithm for the selection of dynamic ROIs to allow the construction of kymographs of proteins associated with the mitotic spindle in Drosophila embryos. We segment a dividing nucleus using a level set coupled to a shape model, which we then use to align the segmented nuclei to a common frame of reference.

  • Manipulation of green LED in chicken egg incubation

    This study was conducted to evaluate the effect of a 12 hours light, 12 hours dark (12L: 12D) photoperiod of green light during day 1 to day 18 of incubation time, on embryo growth and the hatch process. In the test group, monochromatic light was provided by a total of 204 green LEDs (522nm) mounted in a frame which was placed above the top tray of eggs to give even spread of illumination. The control group has no light-dark cycle. Four batches of eggs (n=300 per group per batch) from fertile Ross 308 broiler breeders were used in this experiment. The beak length and crown-rump length of embryos incubated under green light were significantly longer than that of control embryosat day10and day 12, respectively (P&lt;;0.01). Furthermore, green light exposed embryos had a longer third toe length compared to control embryos at day 10, day14 and day17 (P=0.02). The individual hatching time of the light exposure focal chicks (n=33) was 3.4h earlier (P=0.49) than the control focal chicks (n=36). The results of this study indicate that green light accelerates embryo development and results in earlier hatching.
