Natalya Rozanova, PhD

Natalya Rozanova

Senior Embryologist, Lab Director


Dr Rozanova has an extensive scientific and clinical embryology background. She received her masters in Human Physiology and Embryology from the Department of Embryology, Moscow State University in 1993 and doctorate in Developmental Biology in 1999 from the Institute of Developmental Biology, Russian Academy of Sciences, Moscow, Russia.

She has international experience as a senior embryologist and Lab director in different IVF laboratories and hospitals, and has consulted with labs in the USA, Ukraine, and Russia. She is certificated in the principles and practice of clinical research, new methods in infertility, embryo transfer to a uterine cavity, cryopreservation and vitrification of embryos. Dr. Rozanova actively participates in international conferences for human reproductive problems and has authored articles on embryology.

Dr. Rozanova's expertise in clinical embryology include: in vitro fertilization, embryo culture and grading, ICSI, embryo transfer, vitrification, assisted hatching, and PGD (biopsy, fixation, and immunochemistry). She's been actively involved in setting up new IVF labs, establishing procedural protocols, setting quality control, the training of laboratory personnel, cryopreservation, and troubleshooting. Dr. Rozanova has extensive molecular embryology training in primer design, DNA cloning, RNA and DNA extraction, agarose-formaldehyde gel electrophoresis, DNA plasmid purification, bacterial protein expression, PCR, RT-PCR, SYBR GREEN quantitative PCR, DNA sequencing, and in vitro mRNA transcription. Additionally, she is an expert in aseptic technique, stem cell culture, establishment of new primary embryo cells in culture (ESL), genotyping, EB culture, ESL electroporation, and ESL injections in blastocysts.

Her scientific background includes being part of a team at the National Institutes of Health, National Institute of Environmental Health Sciences in Research Triangle Park, NC, USA. Dr. Rozanova's studies involved the potential roles of the protein kinase ? substrates MARCKS and MLP on the formation of the central nervous systems in early embryos. She demonstrated that antisense oligonucleotide "knockdown" of maternal MARCKS transcripts to less than 10% of normal in early Xenopus development has profound consequences on the process of gastrulation and development of the neural tube in this species. Dr. Rozanova has developed several mouse lines of MARCKS –/– and +/+ ES cells that also express, as a marker, the beta-galactosidase and several lines of double MARCKS –/– & MLP –/–. She has used these ES cells to generate chimera embryos to analyze the effects of MARCKS deficiency on neuronal cell migration during forebrain and retina development.

Dr. Rozanova's main interest is to improve laboratory outcomes. Her experimental discoveries and continued high-quality work as a clinical embryologist, as well as her unique talents and expertise, are fundamental to improving health care progress in the field of infertility and in the training of newcomers to this field.

Natalya has 3 children and resides in Moscow, Russia. She is fluent in English, Russian, and Ukrainian.
