Three scientific directions:

Three distinct but interrelated research directions are active in the laboratory:

Cellular systems in muscle regeneration
Adult muscle usually regenerates very efficiently. However when regeneration fails, for example due to repeated damage or alterations in the inflammatory milieu, deposition of fibrotic matrix infiltrated with adipocytes takes place and initiates a vicious circle that prevents functional restoration and interferes with therapeutic approaches. We identified and isolated the progenitors responsible for such “fibrofatty infiltration”. These perivascular mesenchymal cells were initially called fibro-adipogenic progenitors (FAPs) due to their prevalent developmental potential, but recent work from the Goldhamer lab has clearly shown that the same cells are the origin of the ectopic ossification often observed after extensive muscle damage and that they can be induced to acquire an osteogenic phenotype by exposure to BMP2 in vitro. Thus, we now believe these cells to represent the in vivo counterparts of mesenchymal stem cells (MSCs).

From the point of view of progenitor activity, the response of skeletal muscle to damage can be divided in two main phases:

Expansion phase (first 3-4 days following damage) Muscle resident MSCs respond to acute damage by entering a proliferative phase that coincides with the expansion of myogenic progenitors (satellite cells). During this phase, activated MSCs provide trophic support from myogenic cells, and the molecules involved in this crosstalk are the objects of intense investigation in the lab. Throughout this phase inflammatory macrophages reach the tissue through the bloodstream (also called M1 type) and represent the predominant type of inflammatory cells.

Extinction phase (from day 4 to day 7 after damage) As satellite cells abruptly cease to proliferate, they differentiate, fuse to damaged myofibers and return to pre-damage numbers. When regeneration is efficient, a similar fate is met by MSCs. During this phase, M1 macrophages rapidly decrease and are replaced by M2-type, pro-regenerative macrophages. However, if regeneration is inefficient, these cells are retained in the tissue and differentiate in fibrogenic cells as well as adipocytes, initiating fibrofatty degeneration. Another focus of our work is the identification of the cellular and molecular mechanisms underlying their disappearance, and how they fail during the establishment of fibrosis.

Role of innate immune cells Marcophages are required for proper regeneration, which can be disrupted by blocking either the M1-M2 transition, or by preventing the first wave of circulating monocytes from reaching the tissue from the circulation. In both cases, the result is the deposition of fibrotic matrix and the appearance of adipocytes. The interplay between satellite cells, monocytes and MSCs is a key interest of the laboratory.

Microglia/macrophages in CNS pathology
Micorglia are essentially indistinguishable from mature tissue macrophages, but have different functional properties. The investigation of the relative role of these inflammatory cell subsets in CNS pathology has been hindered by the fact that the method routinely used for the generation of chimeric mice requires myeloablation by irradiation, which affects the blood-brain barrier, and the forced mobilization and injection in the bloodstream of hematopoietic progenitors that would normally not exit the bone marrow environment. This leads to the artifactual replacement of microglial cells with bone marrow derived cells. We use an alternative method method to generate chimeras which is alternative method to generate chimeras which is based on parabiosis (the surgical joining of two immunocompatible adult mice leading to blood sharing) we were able to show that microglia is capable of self renewing within the CNS and it is not dependent on bone marrow resident hematopoietic stem cells. This finding was later confirmed by others, which showed that microglia originates from yolk sac hematopoiesis early during development, and not from bone marrow hematopoietic stem cells. Taking advantage of this unique system, we have recently shown that blood derived cells infiltrating the CNS cause the progression of EAE, a mouse model of Multiple Sclerosis to paralysis stages. In addition, we also realized that even when bone marrow derived cells enter the CNS they are unable to replace the endogenous microglia, and they eventually disappear

Ongoing work in the lab addresses questions such as:

What molecular differences allow microglia but not bone marrow derived macrophages to self renew in the CNS? What determines whether innate immune cells cross (e.g. in MS) or not (e.g. following axotomy or in ALS) the blood brain barrier? How do microglia and bone marrow derived myelomonocytic cells change from induction to remission of EAE?

Epigenetic control of lineage choice/differentiation
The last decade of work and the recent Nobel prize awarded for reprogramming has made it clear that cell identity is established and maintained by combinations of transcription factors. A role for epigenetic regulators such as histone methyltransferases in establishing and maintaining cell fate has been hypothesized, but investigations of the role of these enzymes in complex biological systems have lagged behind their biochemical characterization. To bridge such gap, we have generated floxed alleles of two SET-domain (methyltransferase) containing genes encoding for putative methytransferases. Based on in vitro experiments SET7/9 had been described as a H3K4 monomethyltransferase (now questioned) capable of methylating a number of important transcription factors including p53 and the estrogen receptor. Despite reports that SET7 activity is a requirement for these transcription factors to function, KO mice for SET7/9 were viable, fertile and did not display any defect in p53 pathways. As these data was controversial and anti-dogmatic, it took over three years of a rather byzantine review process for this work to be published. This should function as a cautionary tale on the dangers of basing strong biological conclusions on in vitro data, and as a message to reviewers and editors that resistance is futile, and that eventually the truth will prevail and they will publish our papers! Further investigations in the role of SET7/9 are ongoing in collaboration with the Zaph laboratory.

EHMT2/G9a is a H3K9 dimethyltransferase, although it has been suggested that it may also methylate other residues on histone tails. Complete KO of this enzyme was shown to lead to early lethality, prompting us to generate a floxed allele to analyze its roles in adult organisms.
In particular, we have focused on the analysis of its role in hematopoiesis. To our surprise, G9a deletion did not lead to an overt phenotype, and although alterations in T-cell polarization were characterized and reported by our next-door collaborator Colby Zaph, no defect in stem cells activity was observed when using sensitive competitive transplantation assays.
The first hint of a G9a dependent phenotype in immature hematopoietic cells stemmed from the observation that the colonies formed by G9a KO bone marrow derived progenitors when plated in methylcellulose were significantly smaller than those obtained from control heterozygous animals. This led us to test the role of G9a in leukemia, and eventually to the finding that G9a is required for aggressive acute myeloid leukemia, and that in its absence leukemic cells differentiate at a high rate.
