A visit to Uppsala (Dr. Morrell’s lab)

IMG_20180509_120912Dr. Martínez-Pastor visited Dr. Morrell’s lab at SLU Uppsala (Sweden) last May 2018. He was invited to deliver a seminar (Flow cytometry to evaluate sperm quality). It was a great opportunity to met back old colleagues and to visit the new Division of Reproduction building, a place where many scientists are carrying out top research on biology of reproduction. It was a very intense day, with meetings for preparing new research lines and collaborations. Very soon, updates on that!

Yes, we’ve attended the Intl’ Spermatology meeting!

IMG_20180509_205532Last May 2018 we attended the XIII International Spermatology Meeting in Stockholm, Sweden. We contributed with three communications, two of them being presented as oral communications:

Relación del inmunofenotipo de las células NK en el fallo de implantación repetido

Santillán I., Lozano I., Illán J., Verdú V., Coca S., Bajo-Arenas J. M., and Martinez F. (2015). Where and when should natural killer cells be tested in women with repeated implantation failure? J. Reprod. Immunol. 108, 142–148. doi:10.1016/j.jri.2014.12.009

En este trabajo, realizado conjuntamente con la clínica GineFiv y la Dra. Santillán, describimos la relación entre la presencia de subtipos de las células NK y la ocurrencia del fallo de implantación repetitivo (RIF). Encontramos que las NK se encuentran incrementadas tanto en sangre como en endometrio en pacientes que presentan RIF. No obstante, el estudio en endometrio podría tener mejor valor diagnóstico que el de sangre.

Esta publicación marcó el inicio de una colaboración del grupo de investigación con la clínica GineFIV para analizar las células NK en sangre y endometrio (contrato “Análisis comparativo de inmunofenotipo de células natural killer en mujeres con fallo implantacional idiopático”).

Actualmente continuamos la línea de investigación, tratando de obtener más información sobre el inmunofenotipo de las NK en pacientes con RIF.

Attending the Spanish Association for Animal Reproduction meeting

We just attended the 14th meeting of AERA. It has been a great opportunity to meet colleagues and share our last research in the field. Dr. Felipe Martínez-Pastor participated in a satellite meeting on the problems and development of the research career, aimed at young researchers.

We also took the advantage to celebrate the first meeting of our Network for In Vitro Production of Embryos (Red PIVE), supported by a project from the Economy Ministry.

Itxaso Crespo and Amer Salman, Ph. D. candidates in our group also attended, and participated in one of the meetings of the Network too.

We have contributed to the meeting with the following posters (two of them reflecting our collaboration with SERIDA):

Caamaño JN, Salman A, Martínez-Pastor F, Fueyo C, Tamargo C, Carbajo M, and Hidalgo CO. Assessment of chromatin status in the semen bank of the Spanish native cattle breed “Asturiana de la Montaña”. 14th Conference of the Spanish Association for Animal Reproduction (AERA). 2017. Barcelona, Spain. Reprod Domest Anim 52 Suppl. 4:86-87.

Participation in the SEBD-SEBC-SEG Joint Congress

The Spanish Society of Cell Biology (SEBC) celebrated its bianual scientific meeting jointly with the Spanish Societies of Developmental Biology (SEBD) and Genetics (SEG), in Gijón. Estela Fernández and Felipe Martínez attended the meeting, contributing with the poster:

Fernández-Alegre E, Herrero-González A, Rey S, Casao A, and Martinez-Pastor F. Presence of melatonin synthesis enzymes in the reproductive tract of bull. Spanish Society for Cell Biology (SEBC), SEG, SEBD. octubre 2017. Gijón, Spain. Proceedings of the Joint Congress SEG-SEBC-SEBD.
