Although classified as hematopoietic cells, tissue-resident macrophages (MFs) arise from embryonic precursors that seed the tissues prior to birth to generate a self-renewing population, which is maintained independently of adult hematopoiesis. Here we reveal the identity of these embryonic precursors using an in utero MF-depletion strategy and fate-mapping of yolk sac (YS) and fetal liver (FL) hematopoiesis. We show that YS MFs are the main precursors of microglia, while most other MFs derive from fetal monocytes (MOs). Both YS MFs and fetal MOs arise from erythro-myeloid progenitors (EMPs) generated in the YS. In the YS, EMPs gave rise to MFs without monocytic intermediates, while EMP seeding the FL upon the establishment of blood circulation acquired c-Myb expression and gave rise to fetal MOs that then seeded embryonic tissues and differentiated into MFs. Thus, adult tissue-resident MFs established from hematopoietic stem cell-independent embryonic precursors arise from two distinct developmental programs.
Objective: Despite extensive study of the obesity epidemic, research on whether obesity has risen faster in lower or in higher socioeconomic groups is inconsistent. This study examined secular trends in obesity prevalence by socioeconomic position and the resulting obesity inequalities in the German adult population.
Approximately 10 percent of Americans have diabetes and at least 33 percent of American adults are considered prediabetic. The increasing loss of beta-cell function is one of the key factors in the pathogenesis of type 2 diabetes. Over time, increased insulin resistance and beta-cell dysfunction can lead to serious health complications in diabetics. Research efforts have begun to focus on the effects of certain interventions on insulin resistance and beta-cell function at the early stages of the disease. The Restoring Insulin Secretion (RISE) Adult Medication Study was established to determine if pharmaceutical treatment could preserve or improve beta-cell function in adults with prediabetes or recent onset type 2 diabetes.
The purpose of the RISE Adult Medication Study was to determine if pharmacologic intervention could sustain or enhance beta-cell function in adults who were prediabetic or recently diagnosed with type 2 diabetes, and if the effects could be maintained after treatment withdrawal.

Representing 25 years of empirical study on addiction, pharmacology, behavioral health, and criminal justice, these Standards are the foundation upon which all adult drug courts must operate. They hold the keys to transform how the justice system responds to people in crisis.
Since 1987, RISE has provided practical, professional, and personal growth opportunities for children, adults, and their families. With our innovative approach, we are dedicated to transforming the lives of the individuals and families we serve through the delivery of person-centered services.
Our services have expanded from moving individuals living in institutions to family settings into supporting adults and children with highly diverse support needs in a wide variety of homes and community-based settings.
Gap years are usually associated with the brink of adulthood. For those with the time and resources, taking several months to travel, volunteer, or simply relax is one way to reset before pursuing higher education or entering into the workplace. But some adults are breaking the mold by embarking on their own long-term adventures in the form of an adult gap year, also known as a career break. It can mean anything from a three- to six-month-long company-approved sabbatical to abandoning everything to hit the road for a year or longer.
Merkel cells (MCs) are located in the touch-sensitive area of the epidermis and mediate mechanotransduction in the skin. Whether MCs originate from embryonic epidermal or neural crest progenitors has been a matter of intense controversy since their discovery >130 yr ago. In addition, how MCs are maintained during adulthood is currently unknown. In this study, using lineage-tracing experiments, we show that MCs arise through the differentiation of epidermal progenitors during embryonic development. In adults, MCs undergo slow turnover and are replaced by cells originating from epidermal stem cells, not through the proliferation of differentiated MCs. Conditional deletion of the Atoh1/Math1 transcription factor in epidermal progenitors results in the absence of MCs in all body locations, including the whisker region. Our study demonstrates that MCs arise from the epidermis by an Atoh1-dependent mechanism and opens new avenues for study of MC functions in sensory perception, neuroendocrine signaling, and MC carcinoma.
In this study, we investigated the developmental origin and adult maintenance of MCs as well as the genes involved in MC specification. Lineage-tracing experiments using epidermal-specific CRE demonstrated that all MCs, including MCs of whiskers and touch domes of the foot, are derived from epidermal cells. Conditional deletion of Atoh1/Math1 in the embryonic epidermis resulted in the absence of MCs, demonstrating that Atoh1 expression in epidermal progenitors is required for MC specification at all body locations. During adult homeostasis, maintenance of the MC pool is ensured, at least in part, by the differentiation of epidermal SCs. Our study resolves a long-standing controversy regarding the developmental origin of MCs and opens new avenues to study the role of MCs in sensory perception, neuroendocrine functions, and cancer formation.
To determine whether MCs arise from epidermal progenitors, we assessed whether early specified MCs coexpress basal embryonic epidermal progenitor markers such as K14 or K5. At E17, soon after their specification, most of the early specified MCs of the whisker (75 3%) but also of the back skin (64 2%) and paw epidermis (78 4%) coexpressed K14 basal epidermal marker (Fig. 1 C), suggesting that MCs may arise from epidermal progenitors. These early specified MCs also expressed placental cadherin (P-cadherin), which is a marker of embryonic epidermal progenitors (Fig. 1 D). However, shortly after their specification, MCs progressively stopped expressing markers of basal epidermis (at P1, around 20% of MCs coexpressed K14), and in adulthood, MCs no longer expressed K5 or K14 (Fig. S2). The cells coexpressing K14 and MC markers during embryonic development may be the previously described transitional cells seen by electron microscopy, which were thought to represent the transition from epidermal cells to MCs (Tachibana and Nawa, 1980). Furthermore, the demonstration that early specified MCs coexpress P-cadherin, a marker of embryonic hair follicle (HF) progenitors (Rhee et al., 2006), and the absence of MC specification in Tabby mutant mice (Vielkind et al., 1995), which present defects in HF morphogenesis, suggest that HF progenitors and MC specification could be tightly linked.
To determine whether the maintenance of a steady-state number of adult MCs could be ensured by a pool of undifferentiated MCs, we determined whether some MCs proliferate during adult homeostasis. MCs are well known to be quiescent because they do not express proliferation markers (Vaigot et al., 1987; Moll et al., 1996b). To determine whether a few MCs are able to proliferate, we administrated BrdU to mice for 10 d, a protocol resulting in the labeling of most epidermal cells, including quiescent bulge SCs. Administration of BrdU for 10 d resulted in the labeling of most K14-expressing cells (Fig. 4 C), whereas all MCs of the vibrissa remained BrdU negative (Fig. 4 C), suggesting that differentiated MCs are highly quiescent during homeostasis and MC proliferation does not account for the cellular turnover observed by genetic fate mapping.
The absence of MCs in mice lacking Atoh1 in the epidermis offers a novel and powerful model to study the function of MCs during homeostasis and physiopathological conditions. It would be interesting in the future to define which signaling pathways control the differentiation of epidermal progenitors into MCs and whether Notch controls this process as it does during neuroendocrine cell fate specification in the intestine (Jensen et al., 2000; Yang et al., 2001). The demonstration that MCs arise from epidermal progenitors during embryonic development and adult homeostasis offers new avenues to identify the cells at the origin of MC carcinoma, a rare but devastating cancer (Moll, 2006), and to determine whether Atoh1 acts as a tumor suppressor gene in MCs, as has been recently suggested (Bossuyt et al., 2009a,b).
It is estimated that 10.5 million American adults are living with ADHD. A study published in JAMA, reported that diagnosis of ADHD in adults is now four times that of children, and its prevalence more than doubled between 2007 and 2016, from .43 percent to .96 percent. However, other studies suggest even higher rates, ranging from 2.5 percent to 4.4 percent, with more men diagnosed than women. Some researchers suggest that ADHD may be underdiagnosed in adults as well.
Millennials (people born between 1981-1996) have twice the risk of colorectal cancer compared to those born in 1950, according to a 2017 study. The same research found that people under age 55 are nearly 60% more likely to be diagnosed with late-stage disease than older adults. That makes the odds of surviving the colon cancer more challenging.
In May 2021, the U.S. Preventative Services Task Force changed its recommendations for colon cancer screening to begin at age 45, rather than 50. This is because of the increased diagnoses of colorectal cancer in younger adults.
Nineteen states have adult obesity rates over 35 percent. West Virginia, Kentucky, and Alabama have the highest rate of adult obesity at 40.6 percent, 40.3 percent, and 39.9 percent, respectively. The District of Columbia, Hawaii, and Colorado had the lowest adult obesity rates at 24.7 percent, 25 percent, and 25.1 percent respectively.
