Spaceflight and the Antibody Repertoire. This issue features a paper detailing the bioinformatic workflow developed for assessing the effects of spaceflight on the antibody repertoire (p 2). Top right: Animal Enclosure Module (AEM) hardware was validated on the Rodent Research-1 (RR1) mission. High throughput sequencing (HTS) data sets of RR1 animals were made available by NASA GeneLab and spleen tissues were made available by NASA Ames. These were mined for antibody repertoire assessment. Bottom right: Antibodies are heterodimers of heavy (IgH) and light immunoglobulin chains that are encoded on separate loci. A diagram of the IgH locus is pictured. Multiple copies of Variable- (V), Diversity- (D), and Joining- (J) gene segments exist within the germline IgH locus. Somatic recombination at the IgH locus during early B-cell development yields immunoglobulin sequences with one V-D-J-gene segment combination, collectively resulting in a repertoire of antibody specificities that can bind to antigens for host defense. Background image: The antibody repertoire can be characterized by assessing gene segment usage in HTS data sets. Image credits: AEM: NASA, picture of C57BL/6 Mouse: Chapes laboratory (not to scale).

Taking plants to space. This issue features several papers describing preparations and calibrations necessary for developing plant spaceflight payloads, and images from this theme are included in the cover collage. Top left: Fitzgerald (p 8), the optimization of Light rail system using far-red LEDs to impose dormancy on Arabidopsis seeds to aid in their transport to the ISS, along with a scanning electron micrograph of a dormant Arabidopsis seed. Top right: Vandenbrink (p 38), an image of terrestrially-grown Arabidopsis seedlings in an EMCS cassette overlaid with an image of seedlings grown in the EMCS hardware on the ISS. Bottom right: LeFrois (p 28), three different genotypes of Arabidopsis slated for an upcoming flight experiment overlaid with the graphical representations of DNA methylation levels in a gene of interest. Middle left: Hutchinson (p 20), a stack of 60 mm nutrient agar Petri plates that have been densely plated with Arabidopsis seeds for use in the BRIC spaceflight hardware, along with a plate showing germinated Arabidopsis seeds after growing four days in the dark.

Differentiated human blood derived endothelial cells expressing von Willebrand factor, a characteristic endothelial cell marker. Cells cultured under simulated microgravity using microcarrier beads and a rotating wall vessel bioreactor. The effect of simulated microgravity was studied to better understand vascular health following spaceflight.
