Model System | Ai9-SauSpyCas9 mouse | Using CRISPR/Cas9 genome editing in mouse embryos, the existing Rosa-CAG-LSL-tdTomato-WPRE conditional allele Gt(ROSA)26Sortm9(CAG-tdTomato)Hze (commonly referred to as Ai9) was modified to duplicate the guide target sequences for S. pyogenes and S. aureus Cas9 found on the 3' end of the loxP-flanked stop cassette [SpyCas9 5'GTATGCTATACGAAGTTAT (PAM AGG); SauCas9 5'ACGAAGTTATATTAAGGGTT(PAM CCGGAT)] onto the 5' end of the stop cassette. With this modification, a single guide RNA for S. pyogenes or S. aureus Cas9 can be used to mediate deletion of the stop cassette by non-homologous end joining and activation of tdTomato expression. | Baylor College of Medicine | |

Experiment | Cre Recombinase dose escalation study in Ai9 mice | A single stranded cmv cre cassette was packaged into AAV9 or AAVcc47 and injected intravenously in Ai9 mice. We injected n=3 at three different doses (1e10, 1e11, 1e12 vg) and harvested organs 4 weeks post injection. Fluorescence intensity in liver, heart, and skeletal muscle was quantified with tiff based images in Image J and neuronal transduction from each vector was quantified at the 1e12vg dose by counting the number of tdTomato+ neurons and number of NeuN+ cells from multiple sections and images. | ||

Experiment | Comparing CRISPR/Cas9 gene editing efficencies between AAV9 and AAVcc47 in Ai9 mice with a 1:1 cas9 to sgRNA ratio (CMV promoter) | A dual vector strategy was employed: one delivering two single guide RNAs targeting the Rosa26 locus and one delivering CMV driven SaCas9 (both single stranded AAV cassettes). This strategy was evaluted with both AAV9 (n=3) and AAVcc47 (n=3) by intravenous injection in Ai9 mice. A total dose of 3e12vg was injected into each mouse (1.5e12vg each vector mixed 1:1) and organs were harvested 4 weeks post injection.

This strategy was evaluted with both AAV9 (n=4) and AAVcc47 (n=5) by intravenous injection in Ai9 mice. A total dose of 2e12vg was injected into each mouse (1e12vg each vector mixed 1:1) and organs were harvested 4 weeks post injection.

This strategy was evaluted with both AAV9 (n=4) and AAVcc47 (n=4) by intravenous injection in Ai9 mice. A total dose of 4e12vg was injected into each mouse and vectors mixed in a 1:1 ratio of cas9 to guide RNA (2e12vg of CMV Sacas9 vector and 2e12vg of the self complementary sgRNA vector) and organs were harvested 4 weeks post injection. Editing efficency was determined by calculating percent TdTomato+ cells normalized to Dapi+ cells in liver and heart. | ||

Publication | A robust and high-throughput Cre reporting and characterization system for the whole mouse brain. | The Cre/lox system is widely used in mice to achieve cell-type-specific gene expression. However, a strong and universally responding system to express genes under Cre control is still lacking. We have generated a set of Cre reporter mice with strong, ubiquitous expression of fluorescent proteins of different spectra. The robust native fluorescence of these reporters enables direct visualization of fine dendritic structures and axonal projections of the labeled neurons, which is useful in mapping neuronal circuitry, imaging and tracking specific cell populations in vivo. Using these reporters and a high-throughput in situ hybridization platform, we are systematically profiling Cre-directed gene expression throughout the mouse brain in several Cre-driver lines, including new Cre lines targeting different cell types in the cortex. Our expression data are displayed in a public online database to help researchers assess the utility of various Cre-driver lines for cell-type-specific genetic manipulation. | ||

Publication | Canalostomy As a Surgical Approach to Local Drug Delivery into the Inner Ears of Adult and Neonatal Mice. | Local delivery of therapeutic drugs into the inner ear is a promising therapy for inner ear diseases. Injection through semicircular canals (canalostomy) has been shown to be a useful approach to local drug delivery into the inner ear. The goal of this article is to describe, in detail, the surgical techniques involved in canalostomy in both adult and neonatal mice. As indicated by fast-green dye and adeno-associated virus serotype 8 with the green fluorescent protein gene, the canalostomy facilitated broad distribution of injected reagents in the cochlea and vestibular end-organs with minimal damage to hearing and vestibular function. The surgery was successfully implemented in both adult and neonatal mice; indeed, multiple surgeries could be performed if required. In conclusion, canalostomy is an effective and safe approach to drug delivery into the inner ears of adult and neonatal mice and may be used to treat human inner ear diseases in the future. | ||

Publication | Cross-species evolution of a highly potent AAV variant for therapeutic gene transfer and genome editing. | Recombinant adeno-associated viral (AAV) vectors are a promising gene delivery platform, but ongoing clinical trials continue to highlight a relatively narrow therapeutic window. Effective clinical translation is confounded, at least in part, by differences in AAV biology across animal species. Here, we tackle this challenge by sequentially evolving AAV capsid libraries in mice, pigs and macaques. We discover a highly potent, cross-species compatible variant (AAV.cc47) that shows improved attributes benchmarked against AAV serotype 9 as evidenced by robust reporter and therapeutic gene expression, Cre recombination and CRISPR genome editing in normal and diseased mouse models. Enhanced transduction efficiency of AAV.cc47 vectors is further corroborated in macaques and pigs, providing a strong rationale for potential clinical translation into human gene therapies. We envision that ccAAV vectors may not only improve predictive modeling in preclinical studies, but also clinical translatability by broadening the therapeutic window of AAV based gene therapies. | ||

Experiment | Testing AAV5 for activation of tdTomato in mouse airway club and ciliated cells | AAV2/5 mediated gene editing in the mouse airway was tested by deliverying SpCas9 and guide RNAs targeting the Ai9 transgene in Ai9 transgenic mice. Gene editing quantified by tdTomato activation and cell specific markers for club and ciliated cell types. | ||
Experiment | Testing AAV5 for activation of tdTomato in HEK293T cells | AAV shuttle plasmids expressing SpCas9 and guide RNAs targeting the Ai9 transgene were tested in HEK293T cells by transient transfection. Both delivery and gene editing were detected by fluorescence. | ||
Experiment | Podocyte-specific gene editing in human kidney organoids | Kidney organoids were derived from a human iPS cell line with Ai9 (tdTomato) fluorescence-on reporter knocked into the AAVS1 safe harbor locus. Intact kidney organoids were transfected with CRISPR ribonucleoprotein complexes with and without molecular targeting agent (MTA) specific for podocytes. Genome editing events were detected by induction of tdTomato from the Ai9 reporter. | ||
