In this issue of Simply Blood, Christophe Lancrin is exploring Experimental Hematology by highlighting and deconstructing one of his favorite manuscripts from the ISEH society journal: "CD123 CAR T cells for the treatment of myelodysplastic syndrome."
The power to utilize the adaptive immune system to kill cancer cells has long been recognized to have tremendous therapeutic potential but for many years this remained only an elusive dream. However, over the past few decades, tremendous progress has been made along this front. One notable (and Nobel worthy!) breakthrough was the understanding of immune checkpoints. This helped in the design of effective cancer immunotherapies by removing the “brakes” called PD1 and CTLA4 that restrict the immune response of T lymphocytes against cancer cells. Now, antibodies specific to these molecules have proven to be powerful weapons against cancers previously considered untreatable such as metastatic melanoma.

ISEH July 2019 – Message from the President: Bertie Gottgens

Image
Dear ISEH Friends and Colleagues,

This is my final president’s message before I will be stepping down at the end of the ISEH Annual Meeting in August in Brisbane. It has been a real privilege to work on your behalf, with invaluable support from enthusiastic volunteers from right across the globe as well as our dedicated team at SmithBucklin in Chicago. We are fortunate to see exciting breakthroughs in our field on an almost weekly basis, where ground-breaking discoveries in basic research go hand-in-hand with the development of exciting new therapies. Such breakthroughs critically depend on a vibrant research community, and I believe that we can all be proud of the important contributions that the ISEH has made over the last nearly 50 years to foster exactly this.

I am happy to provide you all with an update on the developing partnership between ISEH and the European Hematology Association (EHA). Over 12,000 delegates attended the annual EHA meeting in June in Amsterdam, which in…

What to expect from Australia’s New World City?

Image
For the first time since 2010, the ISEH scientific community will gather Down Under for the Annual Meeting – an incredible opportunity to discover local talent in the field of hematology but also to explore everything this incredible continent nation has to offer! Australia’s health and medical research industry is amongst one of the most productive in the world, generating nearly 4% of global output despite Australians only representing about 0.32% of the world’s population. In accordance with Australia’s reputation, Brisbane is standing as an internationally significant centre for world-class translational research in hematology. In this collaborative environment, the ISEH Annual Meeting represents the ideal opportunity to bond with Australian medical researchers in the field of hematology and develop a productive network of collaborators from across the world.

This year, the ISEH Annual Meeting will take place in Brisbane, the capital of the Australian state of Queensland. With a s…

How to Review a Scientific Manuscript

Image
Even in the era of open access and non-traditional forms of communication like social media, publication of research findings in peer-reviewed scientific journals remains the major way of disseminating our findings to the broader research community.  As such, appropriate peer-review is crucial for the critical review of new data before the findings are presented to the scientific public.  It seems simple enough right?  All of us read papers and think about what the results mean for our wok and for the field.  But we all have our own opinions about what makes a paper really exceptional.  When I read a paper I always think about why the authors chose to do a certain experiment a particular way, or why they didn’t follow up on this finding more.  So we all have an internal monologue, which serves as our own peer-review.  The people called upon by journals to review manuscripts essentially serve as gate-keepers to ensure rigorous and careful interpretation before the data are made public…

New Investigators: This Year’s ISEH NIC Invited Speaker is…

Image
Every year at the ISEH meeting, the New Investigator Committee (NIC) invites one speaker to present in the New Investigator Award Session. For this year’s meeting in Brisbane, we have invited Marella de Bruijn PhD, Professor of Developmental Haematopoiesis at the University of Oxford. Marella completed her PhD at the University of Rotterdam in 1997 and went on to do postdoctoral training with Profs. Elaine Dzierzak and Nancy Speck, In 2003, Marella started her own lab at the Weatherall Institute of Molecular Medicine at Oxford, where she has focused on understanding the genetic regulation of developmental blood formation. Besides running her research laboratory, Marella has been heavily involved in training and mentorship at Oxford and within ISEH, and is this year’s organizer of the ISEH pre-meeting workshop. In preparation for her invited talk at ISEH, we caught up with Marella to find out more about her interests and her science.

Q&A with Marella de Bruijn:
Q1. How would you desc…

Lab Spotlight: McKinney-Freeman Lab

The major overarching theme of my lab is the basic biology of hematopoietic stem cells (HSCs). We are currently focused on deciphering novel molecular regul…

The ISEH Junior Investigator Grant Writing Workshop—a key to your future success!

Image
Obtaining independent grant funding for a new lab is hard.  We all know it, but it feels bigger and heavier when it’s your own lab on the line.  In 2013 I set up my own lab and submitted my first R01 application.  I felt that I had done my due diligence in preparing for this momentous step – having completed 16 (!) years of postgraduate training.  I had put the work in and knew that this was the next leap I needed to take to really become an independent scientist.  Yet even with the benefits granted to new and “young” applicants, my score on that first R01 fell far short of the funding line. I felt the sting and shame of failure, and it rooted itself in a very dark place in my psyche. Over the next year I worked and worked and worked – mostly alone and in my office, and after a full year submitted a revision of the first grant that I felt could pass muster. I had even paid a professional editing service to help with feedback on that grant. So, when that grant was not even scored, the…

Leading a Research Group in Europe - Part II: United Kingdom

Image
Throughout the next few months ISEH member, Christophe Lancrin, will be highlighting his professional journey working in various European countries. This month we travel to the United Kingdom.


Last month, I have started a series of blogs to give a snapshot of how it is to work in academia in Europe. In the first entry, I presented the French system where tenure track is not common and young scientists who just completed their post-doctoral research could get permanent state-funded positions right away.

In this new entry, I will discuss the British system. For the readers who are based in the US, they will notice similarities between the two countries. In particular, a starting group leader has usually to go through the tenure track process before being awarded a permanent position.

I did my post-doctoral research in the UK at the Paterson Institute for Cancer Research now Cancer Research UK Manchester Institute. Cancer Research UK is one of the largest charities in Europe and provides c…

Exploring Experimental Hematology: Induced Pluripotent Stem Cell Modeling of Malignant Hematopoiesis

Image
In this issue of Simply Blood, Yoon-A Kang is exploring Experimental Hematology by highlighting and deconstructing one of her favorite manuscripts from the ISEH society journal: "Induced Pluripotent Stem Cell Modeling of Malignant Hematopoiesis"

The discovery of a means to induce cellular pluripotency by introducing four transcription factors (Sox2, Klf4, Oct3/4 and c-Myc) (Takahashi et al., 2007) has heralded a global scientific re-thinking of genetics and epigenetics among developmental processes and disease. A decade later, induced pluripotent stem cells (iPSCs) with genome editing technology have now opened doors to help answer questions previously limited in the past. Here is a sneak preview of an excellent review where Mark Chao and Ravindra Majeti cover this line of work and more:

My reason for reading this review:
Disease modeling provides important first steps to understand disease pathology and underlying mechanisms that inform ways to eventually discover therapeut…

Clonal Dynamics at the Stem Cell Level in the Progression of Myelodysplastic Syndrome to Acute Myeloid Leukemia: An Interview with Jiahao Chen

Image
A widely known fact is that patients diagnosed with myelodysplastic syndrome (MDS) are at a significantly increased risk for developing subsequent acute myeloid leukemia (AML).  However, how these clinical entities are related at a clonal level has not been well elucidated, let alone studied at the single-cell-level in comparing stem and blast cell populations from the same individual over time. At last year’s ISEH 2018 meeting in Los Angeles, I met Jiahao Chen, the first author of a recently published paper from Dr. Ulrich Steidl’s lab at Albert Einstein College of Medicine who addressed these knowledge gaps (Chen et al. 2019).  Here are answers to a few follow-up questions about his work that was first reported at the annual meeting.



1.  What is the most important take-home message readers should get from your work?

I would say that the most important message from our work comes from our demonstration that stem cells within MDS and AML have a much higher level of clonal he…
