Breastmilk is Dynamic

Cellular and transcriptional diversity over the course of human lactation

This recent 2022 paper in the Proceedings of the National Academy of Sciences by Dr. Nyqiust and colleagues is a site for sore eyes.

It offers a remarkable, high-resolution portrait of how the cellular landscape of human breast milk (hBM) shifts over time. The authors capture something both scientifically rich and uniquely human: the dynamic, living composition of milk as it adapts to the changing needs of mother and child.

The abstract: “Human breast milk is a dynamic fluid that contains millions of cells, but their identities and phenotypic properties are poorly understood. We generated and analyzed single-cell RNA-sequencing (scRNA-seq) data to characterize the transcriptomes of cells from hBM across lactational time from 3 to 632 d postpartum in 15 donors. We found that the majority of cells in hBM are lactocytes, a specialized epithelial subset, and that cell-type frequencies shift over the course of lactation, yielding greater epithelial diversity at later points. Analysis of lactocytes reveals a continuum of cell states characterized by transcriptional changes in hormone-, growth factor-, and milk production-related pathways. Generalized additive models suggest that one subcluster, LC1 epithelial cells, increases as a function of time postpartum, daycare attendance, and the use of hormonal birth control. We identify several subclusters of macrophages in hBM that are enriched for tolerogenic functions, possibly playing a role in protecting the mammary gland during lactation. Our description of the cellular components of breast milk, their association with maternal–infant dyad metadata, and our quantification of alterations at the gene and pathway levels provide a detailed longitudinal picture of hBM cells across lactational time. This work paves the way for future investigations of how a potential division of cellular labor and differential hormone regulation might be leveraged therapeutically to support healthy lactation and potentially aid in milk production.” (Nyquist et. al. 2022)

Epigenetics and Pregnancy
Epigenetics is the study of environmental signals and their effects on our genes. Our genes are not altered so much as they are read and used differently based on the environmental inputs. Epigenetic effects are critical during the pregnancy period as the environmental signals can alter an offspring’s outcome both in good and bad ways. Making sure that we control for better environmental signal exposure while pregnant can go a long way to protecting our children’s DNA from dysfunction and thus their outcome with health. It is well known that chemicals are generally negative insults to our epigenome while anti-inflammatory whole foods are positive. These epigenetic marks can be conserved over multiple generations making them extraordinarily beneficial or dangerous. Here we will discuss the lifestyle mitigating factors for a positive pregnancy and newborn outcome….plus an ode to Brenda Wassum.

Pregnancy is a super important time. Do not take by inhalation, ingestion or other exposure anything that is a potential toxin for the body.
Things to avoid:
1) Caffeine – in low to minimal doses, it is clear that caffeine is safe for pregnant women and their offspring. Caffeine easily crosses into the placenta and thus the baby’s circulation. In utero babies cannot metabolize caffeine well putting them at risk with increasing exposure. The data does not support the same reality for more moderate to high doses. Caffeine is known to raise blood pressure and heart rate in all users in variable numbers based on metabolism capabilities…… plus a literature review and a recipe.

Dr. M’s Women and Children First Podcast #58 – Mahmoud Ghannoum, Ph. D. – Microbiomes – Bacterial and Fungal

This week’s guest is Professor Mahmoud Ghannoum. For over four decades, Dr. Ghannoum has been exploring a critical but neglected inhabitant of the human body, the fungus. Born and raised in Lebanon, Dr Mahmoud Ghannoum is the current Director of the Center for Medical Mycology at Case Western Reserve University. He began his scientific journey at Loughborough University in England where he studied the fungus candida and its health associated diseases. Coupling this work to his curiosity about the whole area of intestinal microorganisms in the human body, he has become one of the leading researchers in the world in this space.
His discoveries include the knowledge that fungal organisms constitute an essential part of the microbiome. In fact, in 2010, Dr Ghannoum was the first scientist to identify over 100 native species of fungi in the oral cavity and that they are mostly friendly to us. Like with bacteria, there are good fungi as well as bad fungi. And just as it was startling to discover that we need positive bacteria in our guts, most people today are shocked to learn that their health depends on flourishing colonies of helpful fungi. Symbiosis in all things seems to be the flavor of the day and history has proven this to be what we should have always assumed.
He is widely published in top journals as well as being the founder and director of Biohm, a company dedicated to microbiome analysis and management from the perspective of fungal and bacterial communities. He is the author of Total Gut Health. This week, Dr. Ghannoum and I look critically at the microbiome of humans from the well trafficked bacterial road to the less travelled fungal road.

Maternal Microbiome Part II
Mom has a gut microbiome that directly seeds her babies microbiome. This microbiome dictates human long term and short term health. Eating a diet loaded with fiber based fruits, legumes and vegetables will cause a highly diverse bacterial microbiome to exist and this existence is correlated with better long term health……plus a section on mate matching as well as the recipe of the week!

This week on the show, I sit down to put the recent four maternal/child health podcasts into perspective. How are these four experts tied together? We, again, examine the basic underpinnings of maternal health risks through the eyes of these thought leaders in preparation for the next series of discussions. Laying important foundations to build our health literacy upon, is critical in my mind. This show is also a way for the folks that are “on the go” to get a summary of the podcasts for their benefit.

Enjoy,

Dr. M
