Our Logo
In April 2017 the logo of the IGBB was changed from a "binary helix" (Figure 1A) to a simpler "pinwheel" design (Figures 1B-1D). Both the old (IGBB 2011) and new logo (IGBB 2017) feature the letters IGBB in caps in a modified Bank Gothic Pro font.

Figure 1. IGBB Logo. (A) The retired 2011 logo and wordmark. (B-D) 2017 logo and wordmark. The images in B, C, D, and E show preferred representations on gray, white, maroon, and black backgrounds, respectively.
The six-part "pinwheel" in the 2017 IGBB logo is:
- A symbol of lab unity as it shows "parts" coming together to make a "whole."
- A flower or three-leaf clover representing (a) plants, important subjects of our research, (b) life in general, and (c) the life sciences (biology).
- A set of chromosomes being moved towards the center of a cell.
- The Sun - another symbol of life.
- A protein composed of six subunits (e.g., a protein pore).
- Three foxes putting their heads together. The fox is a symbol of cleverness in Western folklore. Since the IGBB is organized into three service groups (Genomics, Proteomics/Metabolomics, and Biocomputing/Computational Biology), the foxes could represent the three disciplines working together.
- A scientist jumping for joy after making an important discovery.
- A windmill, the primary symbol associated with Cervantes' famous character Don Quixote - Like Don Quixote, scientists must be willing to attack 'wicked giants' (e.g., ignorance, racism, sexism, intolerance, use of the term 'science' in the promotion of non-scientific causes), champion worthy causes (e.g., education, intellectual freedom, human rights, environmental responsibility), and remain optimistic in the face of defeat (e.g., most days in the lab). Hopefully, however, the average scientist can accomplish these tasks without becoming delusional (a problem that squashed Quixote's dreams of becoming a plant molecular biologist).
- A DNA double-helix or protein in cross section.
- Antibodies binding to a protein.
- Whatever you want it to be.
The decision to replace the 2011 logo was based upon...
- The fact that the double-helix symbol is used in many/most logos of genomics institutes and businesses; we love the double helix and all it represents, but wish to have a logo that is different.
- The desire to have a logo that represents life at various resolutions (high resolution = DNA, proteins, and chromosomes; mid-resolution = a flower, a windmill, foxes, a research team; low resolution = Life, the Sun).
- The Director's love of abstract artworks (e.g., paintings, songs, poetry, symbols) that allow the viewer/listener to interpret the work in a way that may give it a new and unique meaning.

In vitro embryo production (IVP) procedures frequently include supplements such as serum and/or co-culture with various types of somatic cells. However, the presence of undefined serum in culture media introduces a variation from batch to batch, increases viral or prion contamination risk, and leads to problems during fetal development. The aim of the present study was to investigate the possibility of using chemically defined-synthetic serum substitute (SSS) in place of fetal calf serum (FCS) during maturation and long-term culture to stimulate in vitro maturation (IVM), fertilization (IVF) and subsequent embryo development. In Experiment I, the effect of the protein source on in vitro maturation was tested by maturing oocytes in culture media supplemented with 10% FCS (Control Group), 10% SSS (Group I) and 10% SSS+10 ng/ml epidermal growth factor (EGF) (Group II). In Experiment II, effects of SSS on both oocyte maturation and embryo development during in vitro culture (IVC) were tested by maturing oocytes in media supplemented with 10% FCS (FCS Group) or 10% SSS+10 ng/ml EGF (SSS Group), followed by IVF and IVC in SOF media supplemented with 10% FCS and 10% SSS on day 4 for FCS and SSS Groups, respectively. Even though rates for cleavage and development to blastocyst stage were not different, blastocyst cell numbers were higher in Group II containing SSS and EGF. The SSS supplementation group had higher apoptotic nuclei as compared to the FCS Group in Experiment II. Transcripts for heat shock protein 70 (Hsp70), interferon tau (IF-tau), DNA methyltransferase 3a (Dnmt3a), desmosomal glycoprotein desmocollin III (DcIII) and insulin-like growth factor II receptor (Igf-2r) were altered in different culture conditions in Experiment I. However, only glucose transporter-1 (Glut-1) mRNA was different in the SSS and FCS Groups in the second experiment. In summary, SSS and EGF in maturation medium and replacement of FCS with SSS alone in culture medium on day 4 of IVC support oocyte maturation and embryo development in vitro. However, significance of culture condition induced changes on the genome-wide abundance of messenger ribonucleic acid and the significance of the apoptotic nuclei during fetal development still remain to be determined.
